Description

Diethylamine hydrochloride (CAS 660-68-4 ), also referred to as Diethylamine HCl, is the stable salt form of diethylamine produced by neutralization with hydrochloric acid. It functions primarily as a chemical intermediate and preservation agent across pharmaceutical, personal care, and water treatment applications. In pharmaceutical manufacturing, it serves as a key intermediate. This compound is used in the synthesis of active ingredients, particularly where a controlled, non-volatile amine source is required. Personal care formulators incorporate it into preservation systems. It is used in pH-adjusted formulations where amine reactivity must be moderated for product stability. Water treatment programs use it as a biocide precursor and process chemical to control microbial growth. Its role as a stable amine salt also makes it suitable for use in buffer preparation and analytical reagent applications. Diethylamine hydrochloride is supplied as a white crystalline powder. It is available in technical and pharmaceutical grades, with pharmaceutical-grade material typically meeting USP or Ph. Eur. specifications for industrial use. Packaging is offered in standard drum and bulk quantities to support both laboratory-scale and industrial procurement requirements. This ensures consistent supply for various manufacturing needs.
