Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-Methyl-N-(2-(4-methyl-5-oxo-3-(thiophen-2-yl)-4,5-dihydro-1H-1,2,4-triazol-1-yl)ethyl)isoxazole-3-carboxamide.
5-Methyl-N-(2-(4-methyl-5-oxo-3-(thiophen-2-yl)-4,5-dihydro-1H-1,2,4-triazol-1-yl)ethyl)isoxazole-3-carboxamide (CAS 1203247-79-3), molecular formula C14H15N5O3S and molecular weight 333.37 g/mol, is a CATO reference standard with documented purity and traceability.
5-Methyl-N-(2-(4-methyl-5-oxo-3-(thiophen-2-yl)-4,5-dihydro-1H-1,2,4-triazol-1-yl)ethyl)isoxazole-3-carboxamide (C14H15N5O3S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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.
As a certified reference material (CRM), 5-Methyl-N-(2-(4-methyl-5-oxo-3-(thiophen-2-yl)-4,5-dihydro-1H-1,2,4-triazol-1-yl)ethyl)isoxazole-3-carboxamide 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.
