Chemical Structure

Dimethylphosphinicacid CAS 3283-12-3 chemical structure

Description

The occurrence of Dimethylphosphinicacid is closely related to organophosphorus functionality, a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Dimethylphosphinicacid (CAS 3283-12-3) is a high-purity analytical reference standard with the molecular formula C2H7O2P and a molecular weight of 94.05 g/mol.

Dimethylphosphinicacid (C2H7O2P) contains organophosphorus functionality, a carboxylic acid group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions.

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), Dimethylphosphinicacid 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.
