Undergraduate Chemical Science

The Chemical Science Option of the Bachelor of Science Degree in Chemistry is designed to provide students with a basic understanding of the chemical principles combined with a thorough training in laboratory techniques.

Of the various available options that lead to the B.S. degree in Chemistry, the Chemical Science Option places the greatest emphasis on the core subject of Chemistry. In particular the undergraduate laboratory courses are the foundation of each student's course of study. The choice of suitable electives will help the student to prepare for work or advanced study in areas of the Chemical Sciences.

What is Chemical Science?

The Chemical Sciences occupy a central position in today's rapidly developing world of science and technology. The fundamentals of Chemistry are based on an understanding of the composition and properties of matter, of the interconversions of one form of matter to another form. An understanding of these fundamentals leads one to the greater realm of the Chemical Sciences, where one attempts to understand such diverse topics as chemical biology, the synthesis of new forms of matter from pharmaceuticals to new materials, the chemical phenomena of the human environment and an in-depth comprehension of the chemical physics of matter. A student who elects the Chemical Science Option will have the flexibility needed to enter any of these fascinating fields of study.

Declaring the Major

The Chemical Science Option of the Chemistry Major is open to all Stony Brook undergraduates. Perhaps the ideal time to declare the major is at the beginning of a student's sophomore year. It is usually unwise to postpone the declaration past the beginning of the student's junior year. Students who wish to elect this major should speak to the Director of Undergraduate Studies.

Plan of Study

Freshman students usually begin their studies toward the major by completing their introductory studies in chemistry and mathematics. In the sophomore year studies in organic chemistry are combined with mathematics and physics courses. In the junior and senior years, physical and inorganic chemistry courses are completed as well as a series of advanced chemistry courses.


Chemistry is based upon research. This is why students in the major have so many laboratory courses required for their degree. However structured instructional laboratories can not truly introduce students to independent research. For this experience the student must seek out independent research opportunities. The faculty of the Department of Chemistry welcome qualified undergraduate students into their research laboratories. These opportunities are especially suitable for students in their junior and senior years of study. Interested students should review the research interests of the various faculty members and then discuss the possibilities for independent study or research with the individual faculty members who have the research programs of greatest interest. Each summer there are numerous special research programs available at Stony Brook, at nearby Brookhaven Laboratory and at universities across the country, open to qualified students. Interested students should talk to the Director of Undergraduate Studies several months in advance.


Students who have completed the Chemical Science Option are well prepared for entry level positions in many different industries. Such students are particularly attractive to the chemical industry, the pharmaceutical industry, the pertroleum industry, the electronics industry, the biotechnology industry and the various health care industries. The best jobs go to students with good records and with lots of laboratory experience, including research. Students who earn a degree certified by the American Chemical Society may have an edge (see next section). Many students choose to pursue graduate study in such fields as Chemistry, Biochemistry, Materials Science, Pharmacology or Health Science, at various universities around the nation. Masters degrees are usually obtainable after one and a half to two years additional study. Ph.D. degrees usually require four-five years study beyond the Bachelor of Science Degree. Graduate students usually receive substantial stipends throughout their period of graduate study.


Special internships are available for qualified undergraduate students majoring in the chemical sciences. These programs allow students to combine work in an industrial setting with their academic studies. Students in the program work in an industrial laboratory one or two days a week. In return they receive a salary from the company and academic credit from Stony Brook. Interested students should talk to the Student Affairs Coordinator several months in advance.

Double Majors

Highly motivated students often choose to complete the requirements for two majors. Students choosing to major in chemistry may wish to consider a second major in such fields as engineering chemistry, biochemistry, physics, mathematics or biology. Students completing a double major will have an extra credential when looking for a job or when applying for graduate study. However a double major is certainly not a good idea for everyone. Often a better approach is to choose particular advanced courses as electives, matching one's own interests and abilities. And in all cases students should consider the importance of research and additional laboratory courses.

American Chemical Society Certification

The American Chemical Society is the national organization for chemists in the United States. The Society publishes the most prestigious journals, hosts the major national chemistry conferences, and influences chemical education in the country. The Society sets standards for the undergraduate chemistry programs at American universities. As part of this program, the American Chemical Society's Committee on Professional Training has defined a minimum set of courses that they consider necessary for a student to achieve the skills needed for entry into the chemistry profession. Students who complete these requirements have their degrees certified by the Society. Students receiving certified degrees are eligible for immediate entry into the Society upon graduation. Certification requires the completion of a small number of courses in addition to those required for the major.

Major Requirements for the Bachelor of Science Degree

Candidates for the Bachelors of Science Degree in Chemistry who elect the Chemical Science option must complete the Chemistry Core Requirements of basic chemistry, mathematics and physics courses, plus a series of area requirements unique to the Chemical Science Option. In addition all students must fulfill the Upper-Division Writing Requirement.

All required courses must be taken for a letter grade; P/NC grades are not acceptable. All of the courses used to fulfilll the requirements of the major (CHE, MAT, PHY, BIO, etc.) must be passed with a grade of C or higher with the exception of three courses for which the grade may be C-. No transferred course with a grade lower than C may be used to fulfill any major requirement.

Completion of the major requirements entails approximately 65 to 67 credits.

The Chemistry faculty recommends that students intending to pursue careers in the Chemical Sciences secure ACS certification along with their Bachelor of Science in Chemistry degree.

    For ACS certification, students electing the Chemical Science Option need to complete the following courses:

    CHE 346/461 ( Biomolecular Structure and Reactivity) or BIO 361 ( Biochemistry I

  4. Additional Areas of Study

    Because knowledge of computer programming is of great value to all chemists, a course in computer programming is recommended.
