Overview
Cysteamine Hydrochloride, chemically known as 2-Aminoethanethiol Hydrochloride, has the CAS number 156–57–0, molecular formula C2H8ClNS, and molecular weight 113.61. It is a white crystalline powder formed by the salification of cysteamine (2-aminoethanethiol) with hydrochloric acid, and is the most stable and commonly used form of cysteamine. Cysteamine Hydrochloride is a small-molecule sulfhydryl-containing compound with significant physiological activity. In animals, it promotes growth hormone (GH) release by depleting somatostatin (SS), thereby exerting growth-promoting effects. Its molecule contains active sulfhydryl (—SH) and amino groups, endowing it with unique reducing and chelating capabilities, making it widely applicable in pharmaceuticals, feed, chemicals, and cosmetics. Cysteamine Hydrochloride is listed in China's "Catalog of Feed Additives" and is applicable to livestock and poultry farming. The national standard GB/T 24832–2009 "Feed Additive – Cysteamine Hydrochloride β-Cyclodextrin Beadlets" was officially implemented on March 1, 2010, providing unified quality standards for the application of this product in the feed industry.
