Chemical Structure

Cetyltrimethylammonium p-toluenesulfonate CAS 138-32-9 chemical structure

Description

The occurrence of Cetyltrimethylammonium p-toluenesulfonate is closely related to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Cetyltrimethylammonium p-toluenesulfonate (CAS 138-32-9), molecular formula C19H42NC7H13O3S and molecular weight 461.79 g/mol, is a CATO reference standard with documented purity and traceability.

Cetyltrimethylammonium p-toluenesulfonate (C19H42NC7H13O3S) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.

As a certified reference material (CRM), Cetyltrimethylammonium p-toluenesulfonate 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.
