Chemical Structure
Description
As a certified reference material (CRM), 4-bromo-1H-benzo[f]indazole 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.
4-bromo-1H-benzo[f]indazole (CAS 2621935-65-5), molecular formula C11H19BrN2 and molecular weight 259.19 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrile group, bromine substitution, 4-bromo-1H-benzo[f]indazole is typically white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 259.19 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
