【Abstract】 The polymorphs A and B as well as a granular solid C of temozolomide were prepared by recrystallization from different solvents. Their characteristics were discussed by means of melting point, infrared spectrophotometry and X\|ray. In addition, the thermostability of A, B and C was studied by the differential scanning calorimetry.更多还原
