Powder diffraction data and preliminary spectroscopic and thermal characterization of pinaverium bromide, a drug used for functional gastrointestinal disorders

Abstract

Pinaverium bromide (C26H41Br2NO4) is an active pharmaceutical ingredient (API) usually prescribed for the relief of spasm and functional gastrointestinal disorders. This work reports its powder diffraction data, Raman and FT-IR spectroscopy and thermal characterization. Indexing of the powder diffraction pattern showed this material crystallizes in a monoclinic unit cell with a = 16.00(4) Å, b = 8.901(2) Å, c = 19.225(4) Å, β = 98.68(3)°, and V = 2808.2(6) Å3.
