Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 3,4-Dibromo-1H-indazol-6-ol (CAS 887568-91-4), a certified reference material (molecular formula C7H4Br2N2O, MW 291.93 g/mol) for analytical method development and quality control.
The molecular framework of 3,4-Dibromo-1H-indazol-6-ol (C7H4Br2N2O) is characterized by an amide group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
As a certified reference material (CRM), 3,4-Dibromo-1H-indazol-6-ol meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
