Description
CATO manufactures 1,3-dimethyl-1H,4H,5H,6H-pyrazolo[3,4-b][1,4]thiazin-5-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.
1,3-dimethyl-1H,4H,5H,6H-pyrazolo[3,4-b][1,4]thiazin-5-one (CAS 13568-76-8) is a high-purity analytical reference standard with the molecular formula C7H9N3OS and a molecular weight of 183.23 g/mol.
Owing to an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, an aromatic ring system, 1,3-dimethyl-1H,4H,5H,6H-pyrazolo[3,4-b][1,4]thiazin-5-one is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 183.23 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
