Understanding Polymorphism and Crystallisation Issues in the Pharmaceutical Industry
Date: 13 February - 17 February 2023
Location: Online Platform
Tutors: Dr John Studley, Dr Will Watson
We are delighted to be offering this course now ON LINE, the three day course is divided up into 5 sessions, dates and times will be set in UK time zone:
Monday, February 13| 2.00pm – 5.00pm, GMT
Tuesday, February 14 | 2.00pm – 5.00pm, GMT
Wednesday, February 15 | 2.00pm – 5.00pm, GMT
Thursday, February 16 | 2.00pm – 5.00pm, GMT
Friday, February 17 | 2.00pm – 5.00pm, GMT
These 5 sessions aim to give chemists and chemical engineers a thorough practical knowledge of crystallisation processes. After an introduction the course will cover crystallisation of compounds (including hydrates and solvates), different methods of crystallisation, polymorphism, salts and co-crystals, crystallisation of chiral compounds and classical resolution, analytical methods for studying the solid state and will finish with some case studies. Real life practical examples will be used throughout the course to exemplify the different aspects of crystallisation and polymorphism. The course will cover all aspects of the subject including crystallization of intermediates as well as final products. In addition, precipitations and amorphous solids will be covered and the differences between amorphous solids and crystalline solids will be discussed.
