6-Bromo-N-(1h-pyrazol-3-yl)-2h-chromene-3-carboxamide (CAS 1281310-11-9), molecular formula C13H10BrN3O2 and molecular weight 320.14 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 6-Bromo-N-(1h-pyrazol-3-yl)-2h-chromene-3-carboxamide (C13H10BrN3O2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
