Chemical Structure
Description
As a certified reference material (CRM), 4-Benzyl-3-methylisoxazol-5(2H)-one meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
CATO supplies 4-Benzyl-3-methylisoxazol-5(2H)-one (CAS 87927-86-4), a certified reference material (molecular formula C11H11NO2, MW 189.21 g/mol) for analytical method development and quality control.
4-Benzyl-3-methylisoxazol-5(2H)-one (C11H11NO2) contains an amino-acid-derived structure, 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
