The Department of Chemistry was established in the year 1979. Initially the department offered the undergraduate courses with Tamil and English as the medium of instruction. During the academic year 1996 -97, as part of UGC's vocationalisation of Education Scheme B.Sc., Chemistry (English medium) course was converted as B.Sc., Industrial Chemistry with UGC's financial assistance.
