Chemical Structure
Description
The occurrence of Tetramethyl Pyrophosphorothioate is closely related to a carbohydrate-derived structure, a sulfone group, a phosphate ester group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Tetramethyl Pyrophosphorothioate (CAS 18764-12-0) is a high-purity analytical reference standard with the molecular formula C4H12O6P2S and a molecular weight of 250.15 g/mol.
Tetramethyl Pyrophosphorothioate (C4H12O6P2S) 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), Tetramethyl Pyrophosphorothioate 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.
