Triethylamine hydrochloride

Triethylamine hydrochloride (CAS 554-68-7), also known as triethylammonium chloride or triethylamine HCl, is the hydrochloride salt form of triethylamine. It carries no assigned E-code and is classified under HS code 29221910 within the amines and their salts category.

In pharmaceutical manufacturing, it functions as a buffering agent and counterion in synthesis reactions, helping to neutralize acid byproducts and stabilize active intermediates. In textile and leather processing, its antimicrobial properties inhibit microbial growth during wet processing stages, reducing spoilage and extending material shelf life.

Triethylamine hydrochloride is supplied as a white to off-white crystalline powder in technical and pharmaceutical-grade formats, subject to REACH registration requirements for EU supply. Buyers should confirm grade suitability against relevant pharmacopoeial standards where pharmaceutical application is intended. Standard packaging options include drums and bags sized for industrial procurement volumes.
