2-Chloro-N,N-dimethylethylamine hydrochloride, also called 2-dimethylaminoethyl chloride hydrochloride or DMC·HCl, is a crystalline alkylating reagent used to attach the 2-(dimethylamino)ethyl group to phenols, thiols, amines and carbanions. It is a hygroscopic white to off-white solid that melts at 201–204 °C, dissolves freely in water and alcohol, and is supplied here at a reference assay of 99%. The free base is a reactive 2-chloroethylamine that cyclises to an aziridinium ion, and the hydrochloride salt is the stable, storable form. This reactivity underpins its role as an intermediate in the preparation of active pharmaceutical ingredients and other fine chemicals that contain a basic dimethylaminoethyl side chain, as well as quaternary ammonium and cationic polymer intermediates. Important notice: this compound is listed in Schedule 2 of the Chemical Weapons Convention and is subject to national controls on production, trade and export. Sarchem Labs lists it for lawful industrial and research purposes only, to purchasers who can meet the applicable regulatory requirements, with a Certificate of Analysis and Safety Data Sheet for each lot.

Product Description

What is 2-Chloro-N,N-dimethylethylamine Hydrochloride?

It is the hydrochloride of N,N-dimethyl-2-chloroethylamine, (CH3)2NCH2CH2Cl · HCl, with a molecular weight of 144.04 g/mol and a melting point of 201–204 °C. The molecule combines a tertiary amine and a primary alkyl chloride two carbons apart, which is the structural pattern of a 2-haloethylamine. Protonation of the nitrogen in the hydrochloride suppresses the intramolecular cyclisation that would otherwise occur, so the salt is the stable form for storage and shipping.

Sigma-Aldrich lists the reference material as 99% pure crystals classed as a combustible solid, with hazard classifications for acute oral toxicity, suspected germ-cell mutagenicity, repeated-exposure organ toxicity and chronic aquatic toxicity.

Uses of 2-Chloro-N,N-dimethylethylamine Hydrochloride

In industrial synthesis, the reagent is released from its hydrochloride with a base in situ and reacts as an alkylating agent. Typical reactions are O-alkylation of phenoxides and N-alkylation of heterocycles, which attach a dimethylaminoethyl chain that improves water solubility and can be quaternised or oxidised in later steps. Process chemists value it as a cost-effective way to introduce this side chain.

Regulatory and Compliance Considerations

Chemicals of this type are controlled because of their potential misuse. Purchasers should be prepared to confirm lawful end use and to meet record-keeping and reporting obligations. Anyone planning to store, ship or export the material should confirm the requirements under the Chemical Weapons Convention as implemented in their country, for example the U.S. Chemical Weapons Convention Regulations, as well as transport, workplace-safety and hazardous-waste rules.

Regulatory Status Notice

2-Chloro-N,N-dimethylethylamine hydrochloride is listed in Schedule 2 (Part B) of the Chemical Weapons Convention. Production, processing, consumption, import and export are subject to declaration, licensing and end-use controls under national implementing laws, and transfers to non-States Parties are prohibited. Sarchem Labs lists the compound for lawful industrial and research customers only, and sale is subject to compliance screening. This page is for information and does not constitute legal advice.
