Benzo[c][1,2,5]thiadiazol-5-yl(7,8-dihydropyrido[4,3-d]pyrimidin-6(5H)-yl)methanone (CAS 1797142-46-1), molecular formula C14H11N5OS and molecular weight 297.34 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Benzo[c][1,2,5]thiadiazol-5-yl(7,8-dihydropyrido[4,3-d]pyrimidin-6(5H)-yl)methanone (C14H11N5OS) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
CATO manufactures Benzo[c][1,2,5]thiadiazol-5-yl(7,8-dihydropyrido[4,3-d]pyrimidin-6(5H)-yl)methanone 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.
