Academic Year 2021/2022 - 3° YearCredit Value: 6
Scientific field: CHIM/08 - Pharmaceutical chemistry
Taught classes: 28 hours
Laboratories: 30 hours
Term / Semester: 1°
Learning Objectives
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.
