Chemical Structure
Description
2-Iodo-6-nitrobenzoic acid (CAS 89641-04-3), molecular formula C7H4INO4 and molecular weight 293.02 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C7H4INO4, 2-Iodo-6-nitrobenzoic acid contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, iodine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 293.02 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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), 2-Iodo-6-nitrobenzoic 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.
