1,1-Dioxido-2,3-dihydro-4H-thieno[2,3-b]thiopyran-4-yl 2,6-difluorobenzoate CAS 343373-67-1

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1,1-Dioxido-2,3-dihydro-4H-thieno[2,3-b]thiopyran-4-yl 2,6-difluorobenzoate.

CATO supplies 1,1-Dioxido-2,3-dihydro-4H-thieno[2,3-b]thiopyran-4-yl 2,6-difluorobenzoate (CAS 343373-67-1), a certified reference material (molecular formula C14H10F2O4S2, MW 344.35 g/mol) for analytical method development and quality control.

Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, a polycyclic aromatic system, 1,1-Dioxido-2,3-dihydro-4H-thieno[2,3-b]thiopyran-4-yl 2,6-difluorobenzoate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 344.35 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

CATO manufactures 1,1-Dioxido-2,3-dihydro-4H-thieno[2,3-b]thiopyran-4-yl 2,6-difluorobenzoate 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.
