Chemical Structure
Description
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
3-Ethyl-N-methyl-5-(2-phenylacetyl)isoxazole-4-carboxamide (CAS 63486-41-9), molecular formula C15H16N2O3 and molecular weight 272.30 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-Ethyl-N-methyl-5-(2-phenylacetyl)isoxazole-4-carboxamide (C15H16N2O3) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
CATO manufactures 3-Ethyl-N-methyl-5-(2-phenylacetyl)isoxazole-4-carboxamide 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.
