Triethanolamine Hydrochloride CAS 637-39-8

Description

Compared with other compounds in its class, the molecular weight of 185.65 g/mol gives Triethanolamine Hydrochloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Triethanolamine Hydrochloride (CAS 637-39-8), molecular formula C6H15NO3HCl and molecular weight 185.65 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Triethanolamine Hydrochloride (C6H15NO3HCl) is characterized by an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
