X-ray powder diffraction analysis of abacavir hemisulfate

摘要

The room temperature powder pattern of abacavir hemisulfate (anti-HIV reverse transcriptase compound) was indexed using 2θ values obtained from a powder pattern spiked with an internal standard. The resulting unit cell values for the monoclinic I2 cell [nonstandard setting of C2 (No. 5)] are a= 13.278(1) A, b =8.437(1) A, c= 14.259(2) A, β=93.87(1)°. There are two formula units [(C_(14)H_(16)N_6O)_2.H_2SO_4] per unit cell and D_x= 1.390 g/cm~3.
