Hello Aspirant,
Yes, you can opt for M.Tech in Pharmaceutical Chemistry and Science after B.Tech provided your B.Tech was in one of the appropriate specializations. Most of the institutes don't clarify the BTech specialization, but look for a candidate coming from Chemical Engineering, Biotechnology, Pharmaceutical Technology etc. if your BTech branch is within these, then you should have a fair eligibility too. Also, you may need valid GATE scores in the appropriate subject for some universities.
