Abstract
Evidence is presented that cortisone acetate occurs in at least five distinct crystalline forms. Four of these forms are unstable in presence of water and change to the stable Form I. Physical data, including spectroscopic and X-ray crystallographic constants, are recorded, and the application of these physical measurements to the recognition of the different forms, and the value of doing this with pharmaceutical preparations are discussedKeywords
