Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2-{3-oxo-2h,3h,5h,7h,8h-thiopyrano[4,3-c]pyridazin-2-yl}acetic acid (CAS 1383626-35-4) is a high-purity analytical reference standard with the molecular formula C9H10N2O3S and a molecular weight of 226.25 g/mol.
The molecular framework of 2-{3-oxo-2h,3h,5h,7h,8h-thiopyrano[4,3-c]pyridazin-2-yl}acetic acid (C9H10N2O3S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).
CATO manufactures 2-{3-oxo-2h,3h,5h,7h,8h-thiopyrano[4,3-c]pyridazin-2-yl}acetic acid 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.
