Essays on recognition of drugs M - Z

Academic Year 2022/2023 - Teacher: SIMONE RONSISVALLE

Expected Learning Outcomes

At the end of the course, which also consists of laboratory exercises in a single place, the student acquires the knowledge and practice for the identification of compounds of pharmaceutical interest, mainly with organic structure, by means of specific chemical assays and instrumental analytical techniques. The student will be able to employ the methods reported in the Italian Official Pharmacopoeia and European Pharmacopoeia.
