Chemical Structure
Description
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.
