Chemical Structure
Description
The molecular framework of (S)-5-Methyl-N-(3-methyl-1-oxobutan-2-yl)isoxazole-3-carboxamide (C10H14N2O3) is characterized by an amino-acid-derived structure, 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
(S)-5-Methyl-N-(3-methyl-1-oxobutan-2-yl)isoxazole-3-carboxamide (CAS 828295-25-6), molecular formula C10H14N2O3 and molecular weight 210.23 g/mol, is a CATO reference standard with documented purity and traceability.
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.
