Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
5-Iodo-3-methoxy-7-methylbenzo[d]isoxazole (CAS 864756-01-4), molecular formula C9H8INO2 and molecular weight 289.07 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 5-Iodo-3-methoxy-7-methylbenzo[d]isoxazole (C9H8INO2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, iodine substitution. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 289.07 g/mol, it falls into the medium-molecular-weight range. 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).
CATO manufactures 5-Iodo-3-methoxy-7-methylbenzo[d]isoxazole under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
