Chemical Structure
Description
3-[3-(4-Methylphenyl)-2,1-benzisoxazol-5-yl]-acrylic acid (CAS 344276-77-3) is a high-purity analytical reference standard with the molecular formula C17H13NO3 and a molecular weight of 279.29 g/mol.
3-[3-(4-Methylphenyl)-2,1-benzisoxazol-5-yl]-acrylic acid (C17H13NO3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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 3-[3-(4-Methylphenyl)-2,1-benzisoxazol-5-yl]-acrylic acid 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.
