The occurrence of Trimethylstearylammonium Bromide is closely related to bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Trimethylstearylammonium Bromide (CAS 1120-02-1), a certified reference material (molecular formula C21H46NBr, MW 392.51 g/mol) for analytical method development and quality control.
The molecular framework of Trimethylstearylammonium Bromide (C21H46NBr) is characterized by bromine 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. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), Trimethylstearylammonium Bromide meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
