Chemical Structure

Cetyltrimethylammonium Chloride CAS 112-02-7 chemical structure

Description

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.

CATO supplies Cetyltrimethylammonium Chloride (CAS 112-02-7), a certified reference material (molecular formula C19H42NCl, MW 320.00 g/mol) for analytical method development and quality control.

The molecular framework of Cetyltrimethylammonium Chloride (C19H42NCl) is characterized by chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
