Paracetamol habit modification by impurities

Research output: Contribution to conferencePoster

Abstract

The presence of impurities during crystallisation can affect final crystal attributes other than chemical purity. For example,metacetamol, a regioisomer of paracetamol, has been reported to modify the morphology of the API, leading to theisolation of columnar crystals in place of crystals with an equant habit. Small scale recrystallisation of pure paracetamolfrom 2-propanol was found here to produce small, relatively equant crystals.
