Subject Title
Organic Chemistry

Subject Description

The lecture section of this Subject includes:

  • The structural and pharmaceutical properties of amines.
  • Theory and practical aspects of mass spectroscopy. . These sets of lectures are intended to include pre-laboratory lecture topics to carry out the data acquisition and data analysis of the qualitative analysis of an unknown mixture by  gas  chromatography coupled with mass spectrometer detector
  • A brief look at the principles of liquid chromatography coupled with electron spray ionization mass spectrometry form part II of the mass spectroscopy theory .
  • The physico-chemical properties that influence the reactivity of drug molecules and correlation of structure and activity.
  • An introduction to the principles of combinatorial synthesis [if time permits or as a self study section].

A portion of the lecture periods will also  be used to explain the theory and procedure details behind the laboratory projects.

Laboratory section of this Subject deals with:
  • A multi-step synthesis of an anaesthetic (lidocaine)
  • The assay of this product by HPLC method.
  • Qualitative mass-spectrometric analysis of an unknown organic compound (or mixture) .
  • Quantitative mass-spectrometric analysis by SIM mode [ if time permits]

Credit Status
If applicable the subject is worth one credit towards a diploma in the Pharmaceutical Technology program.

CHO 433
