1H-indazole-3-sulfonamide, 4-bromo- CAS 162502-01-4

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1H-indazole-3-sulfonamide, 4-bromo-.

1H-indazole-3-sulfonamide, 4-bromo- (CAS 162502-01-4) is a high-purity analytical reference standard with the molecular formula C7H6BrN3O2S and a molecular weight of 276.11 g/mol.

1H-indazole-3-sulfonamide, 4-bromo- (C7H6BrN3O2S) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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), 1H-indazole-3-sulfonamide, 4-bromo- 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.
