Abstract

The invention discloses a method for detecting related substances of sarpogrelate hydrochloride intermediate C. The method is simple, and the precision, accuracy, reproducibility and durability are good. The method can be used for quality control of the related substances of the sarpogrelate hydrochloride raw material intermediate C, namely 1-(dimethylamino)-3-[2-[2-(3-methoxyphenyl)ethyl]phenoxy]-2-propyl-alcohol hydrochloride.

Description

technical field [0001] The invention belongs to the field of drug detection, and in particular relates to a method for detecting related substances containing sargrelate hydrochloride intermediate C. Background technique [0002] Sarpogrelate hydrochloride is a 5-hydroxytryptamine (5-HT2) receptor blocker that can specifically bind to 5-HT2 receptors. 5-hydroxytryptamine (5-HT) was first proposed as a vasoactive substance in 1955. 5-HT exists widely in animals, especially in the cardiovascular system. Except for a small part that is re-uptaked and stored in platelets, almost all 5-HT is inactivated by endothelial cells in the liver and lungs. Sagrelate hydrochloride can specifically bind to 5-HT2 receptors, showing a special antagonistic effect on receptors on platelets and vascular smooth muscle. Therefore, it exhibits anti-platelet effect and inhibits vasoconstriction, and exerts a series of biological effects. Sagrelate hydrochloride is an antithrombotic drug, mainly u...
