3-((3-Chloro-5-(trifluoromethyl)pyridin-2-yl)thio)-2,5-dihydrothiophene 1,1-dioxide CAS 338397-76-5 chemical structure

Description

CATO manufactures 3-((3-Chloro-5-(trifluoromethyl)pyridin-2-yl)thio)-2,5-dihydrothiophene 1,1-dioxide under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.

CATO supplies 3-((3-Chloro-5-(trifluoromethyl)pyridin-2-yl)thio)-2,5-dihydrothiophene 1,1-dioxide (CAS 338397-76-5), a certified reference material (molecular formula C10H7ClF3NO2S2, MW 329.75 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, 3-((3-Chloro-5-(trifluoromethyl)pyridin-2-yl)thio)-2,5-dihydrothiophene 1,1-dioxide is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 329.75 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
