Triethylamine hydrochloride

Triethylamine hydrochloride (CAS 554-68-7), also known as triethylammonium chloride and commonly abbreviated as TEA·HCl, is the stable salt form of triethylamine produced by neutralization with hydrochloric acid.

Where is Triethylamine hydrochloride used?

• Pharmaceutical synthesis: buffering agent and counterion source in API synthesis, where controlled pH and stable amine delivery are critical to reaction yield and purity
• Textile and leather processing: auxiliary in dyebath formulations, improving dye uptake and fixation on fiber substrates
• Paper treatment: supports surface chemistry modifications where controlled charge interaction between fiber and coating agents is required
• Specialty chemical manufacturing: synthetic intermediate in the preparation of quaternary ammonium compounds used in preservation and biocide formulations

Commercial specifications

• Pharmaceutical supply typically conforms to in-house or compendial specifications
• Packaging ranges from small laboratory quantities to bulk industrial supply
