Description
CATO manufactures 5-Methoxy-3-methyl-4-nitroisoxazole 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.
CATO supplies 5-Methoxy-3-methyl-4-nitroisoxazole (CAS 84735-85-3), a certified reference material (molecular formula C5H6N2O4, MW 158.11 g/mol) for analytical method development and quality control.
Structurally, 5-Methoxy-3-methyl-4-nitroisoxazole (C5H6N2O4) contains a carbohydrate-derived structure, an amide group. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 158.11 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
