Description
Compared with other compounds in its class, the molecular weight of 288.04 g/mol gives 3-Iodo-1H-indazole-7-carboxylic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
3-Iodo-1H-indazole-7-carboxylic acid (CAS 2167406-00-8), molecular formula C8H5IN2O2 and molecular weight 288.04 g/mol, is a CATO reference standard with documented purity and traceability.
3-Iodo-1H-indazole-7-carboxylic acid (C8H5IN2O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, iodine substitution. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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), 3-Iodo-1H-indazole-7-carboxylic acid 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.
