摘要： A novel crystalline form of 2,3-dimethyl-1,4-benzoquinone-5-decyl-triphenylphosphonium bromide is provided. The crystalline form was found to have X-ray powder diffraction peaks at 19.25, 21.507, and 23.074 degrees 2 theta, ±0.2 degrees 2 theta. Also provided are industrially feasible methods for manufacture of the crystalline form with high purity.
