Chemical Structure
Description
CATO supplies 5,6,7,8-Tetrahydro-3H-benzo[4,5]thieno[2,3-d]-pyrimidin-4-one (CAS 14346-24-8), a certified reference material (molecular formula C10H10N2OS, MW 206.26 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, 5,6,7,8-Tetrahydro-3H-benzo[4,5]thieno[2,3-d]-pyrimidin-4-one is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 206.26 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 5,6,7,8-Tetrahydro-3H-benzo[4,5]thieno[2,3-d]-pyrimidin-4-one 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.
