Diethylamine hydrochloride

Diethylamine hydrochloride (CAS 660-68-4, also known as diethylammonium chloride or Diethylamine HCL) is the hydrochloride salt form of diethylamine, produced by reacting diethylamine with hydrochloric acid. It carries no assigned E-code and is catalogued under EC 211-541-9 with the molecular formula C4H11N.ClH.

In pharmaceutical manufacturing, it serves as an intermediate in the synthesis of active ingredients and as a pH-adjusting agent in formulations where controlled buffering is required. In water treatment and personal care applications, it functions as a preservation and biocide agent, disrupting microbial cell membranes to inhibit bacterial and fungal growth at low concentrations.

This material is supplied in pharmaceutical and technical grades, with compliance documentation available to support REACH registration requirements. Standard packaging includes multi-kilogram bags and drums suited to industrial procurement volumes. Buyers should confirm grade-specific purity specifications against Ph.Eur. or in-house quality standards prior to ordering.
