Chemical Structure

Dimethylammunonium Sulfate CAS 21249-13-8 chemical structure

Description

As a certified reference material (CRM), Dimethylammunonium Sulfate 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.

Dimethylammunonium Sulfate (CAS 21249-13-8) is a high-purity analytical reference standard with the molecular formula H2O4SC2H7N and a molecular weight of 143.16 g/mol.

Based on its molecular formula H2O4SC2H7N, Dimethylammunonium Sulfate contains an amide group, a sulfone group, a carboxylic acid group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 143.16 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
