Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-Bromo-6-iodo-1,2-dihydro-3H-indazol-3-one.
4-Bromo-6-iodo-1,2-dihydro-3H-indazol-3-one (CAS 887568-51-6), molecular formula C7H4BrIN2O and molecular weight 338.93 g/mol, is a CATO reference standard with documented purity and traceability.
4-Bromo-6-iodo-1,2-dihydro-3H-indazol-3-one (C7H4BrIN2O) contains an amide group, a hydroxyl group, an ether linkage, bromine/iodine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 4-Bromo-6-iodo-1,2-dihydro-3H-indazol-3-one 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.
