Description
CATO supplies Methyl 6-nitro-1H-indazole-3-carboxylate (CAS 1167056-71-4), a certified reference material (molecular formula C9H7N3O4, MW 221.17 g/mol) for analytical method development and quality control.
Methyl 6-nitro-1H-indazole-3-carboxylate (C9H7N3O4) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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), Methyl 6-nitro-1H-indazole-3-carboxylate 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.
