Chemical Structure

O,O-Diethyl Dithiophosphate CAS 298-06-6 chemical structure

Description

O,O-Diethyl Dithiophosphate (C4H11O2PS2) contains a sulfone group, 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.

O,O-Diethyl Dithiophosphate (CAS 298-06-6) is a high-purity analytical reference standard with the molecular formula C4H11O2PS2 and a molecular weight of 186.23 g/mol.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
