IDENTIFICATION OF DRUGS A - L

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.

 

Preliminary testing: Tasting notes, essays Combustion, organic elemental analysis, quantitative elemental analysis, examination of the chemical, solubility assays

Physical Constants: Melting Point, Boiling Point, Density, Refractive index,

Polarimetry (specific rotatory power: determination of specific rotatory power; scheme of the instrument, determination of optical purity).

Recognition of Functional Groups:

Carboxylic acids, hydroxy acids, phenols, alcohols, aldehydes and ketones, esters, anhydrides, ethers, halogen derivatives, amines, amides, amino acids, nitro compounds, hydrocarbons.
