Overview

4-N,4-N-diethyl-2-methylbenzene-1,4-diamine hydrochloride (CAS 2051-79-8) is an aromatic diamine compound with significant industrial applications and specific safety considerations. This specialized chemical compound, also identified by EC number 218-130-3, belongs to the family of substituted benzene diamines with a molecular formula of C11H19ClN2 and molecular weight of 214.73 g/mol. The hydrochloride salt form enhances the compound's stability and handling properties compared to its free base counterpart. As an aromatic diamine derivative, it shares certain structural characteristics with other industrial chemicals like N-methylaniline, though its diethyl and methyl substitution pattern provides distinct chemical properties and reactivity profiles. The compound presents several important safety considerations that require careful handling protocols. Classified under ADR Class 6.1, it carries acute toxicity warnings (Acute Tox. 3) and is designated with the "Danger" signal word. The substance exhibits eye irritation properties (Eye Irrit. 2) and skin sensitization potential (Skin Sens. 1), necessitating appropriate personal protective equipment during handling. Environmental considerations are equally important, as the compound is classified for both acute and chronic aquatic toxicity (Aquatic Acute 1; Aquatic Chronic 1), requiring controlled disposal and environmental protection measures. Industrial applications typically include use as an intermediate in organic synthesis processes, particularly in the production of dyes, pigments, and specialized chemical compounds. The compound's diamine structure makes it valuable in polymer chemistry applications and as a building block for more complex molecular structures. OYSI maintains reliable supply chains for 4-N,4-N-diethyl-2-methylbenzene-1,4-diamine hydrochloride, supporting European industrial customers with consistent quality and comprehensive technical documentation.
