CRYSTAL OF (±)2-(DIMETHYLAMINO)-1-{[O-(m-METHOXYPHENETHYL)PHENOXY]METHYL}ETHYL HYDROGEN SUCCINATE HYDROCHLORIDE

摘要

PROBLEM TO BE SOLVED: To provide a novel crystal of (±) 2-(dimethylamino)-1-ä[O-(m-methoxyphenethyl)phenoxy]methyl}ethyl hydrogen succinate hydrochloride. SOLUTION: The II type crystal and the I type crystal of (±) 2-(dimethylamino)-1-ä[O-(m-methoxyphenethyl)phenoxy]methyl}ethyl hydrogen succinate hydrochloride that can be characterized by at least one of physico-chemical properties selected from the specific diffraction peak in the powdery X ray diffraction peak, the specific endothermic peak in differential scanning calorimetry, the specific peak in solid13C-NMR spectrum and the specific peak in infrared absorption spectrum.
