O-Ethyl O-(3,5,6-trichloropyridin-2-yl) O-hydrogen phosphorothioate CAS 66651-96-5

Description

The occurrence of O-Ethyl O-(3,5,6-trichloropyridin-2-yl) O-hydrogen phosphorothioate is closely related to an amide group, a sulfone group, a phosphonate group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies O-Ethyl O-(3,5,6-trichloropyridin-2-yl) O-hydrogen phosphorothioate (CAS 66651-96-5), a certified reference material (molecular formula C7H7Cl3NO3PS, MW 322.53 g/mol) for analytical method development and quality control.

Owing to an amide group, a sulfone group, a phosphonate group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, O-Ethyl O-(3,5,6-trichloropyridin-2-yl) O-hydrogen phosphorothioate is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 322.53 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
