Chemical Structure
Description
Methyl 3-Hydroxyisoxazole-5-carboxylate (CAS 10068-07-2), molecular formula C5H5NO4 and molecular weight 143.10 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a carbohydrate-derived structure, an amide group, Methyl 3-Hydroxyisoxazole-5-carboxylate is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 143.10 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
CATO manufactures Methyl 3-Hydroxyisoxazole-5-carboxylate 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.
