S-((Bis(4-chlorophenyl)phosphoryl)methyl) ethanethioate CAS 866363-66-8

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including S-((Bis(4-chlorophenyl)phosphoryl)methyl) ethanethioate.

S-((Bis(4-chlorophenyl)phosphoryl)methyl) ethanethioate (CAS 866363-66-8) is a high-purity analytical reference standard with the molecular formula C15H13Cl2O2PS and a molecular weight of 359.21 g/mol.

S-((Bis(4-chlorophenyl)phosphoryl)methyl) ethanethioate (C15H13Cl2O2PS) contains a sulfone group, organophosphorus functionality, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
