Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 4,5,6,7-Tetrahydrothieno[3,2-c]pyridin-2(3H)-one 4-methylbenzenesulfonate (CAS 178688-49-8), a certified reference material (molecular formula C7H8O3SC7H9NOS, MW 327.41 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, 4,5,6,7-Tetrahydrothieno[3,2-c]pyridin-2(3H)-one 4-methylbenzenesulfonate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 327.41 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO manufactures 4,5,6,7-Tetrahydrothieno[3,2-c]pyridin-2(3H)-one 4-methylbenzenesulfonate 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.
