Dimethylamine hemisulfate CAS 37773-96-9 chemical structure

Description

CATO supplies Dimethylamine hemisulfate (CAS 37773-96-9), a certified reference material (molecular formula O4SC2H8N, MW 142.15 g/mol) for analytical method development and quality control.

Dimethylamine hemisulfate (O4SC2H8N) contains an amide group, a sulfone group, a carboxylic acid group, an ether linkage. It is notably hygroscopic, 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), Dimethylamine hemisulfate 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.
