Thiodiphosphoric Acid Tetramethyl Ester CAS 51120-35-5 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 266.21 g/mol gives Thiodiphosphoric Acid Tetramethyl Ester distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Thiodiphosphoric Acid Tetramethyl Ester (CAS 51120-35-5), a certified reference material (molecular formula C4H12O5P2S2, MW 266.21 g/mol) for analytical method development and quality control.

Thiodiphosphoric Acid Tetramethyl Ester (C4H12O5P2S2) contains a carbohydrate-derived structure, a sulfone group, a phosphate ester group. It is notably hygroscopic, 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), Thiodiphosphoric Acid Tetramethyl Ester 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.
