Cysteamine Hydrochloride (Cysteamine HCl) CAS 156-57-0

Product Overview

Cysteamine Hydrochloride is supplied as an aminothiol intermediate used in thiol-mediated reactions, reduction systems, and specialty synthesis processes. It is suitable for pharmaceutical intermediate manufacturing, laboratory synthesis, and selected industrial processing applications where reactive sulfur functionality and good water solubility are required.

This material is commonly handled as a hygroscopic solid and is typically selected where controlled reactivity, salt form stability, and compatibility with aqueous systems are important for process design and formulation handling.
