Description

The occurrence of (Z)-2-Methyl-4-(3-methylbenzylidene)oxazol-5(4H)-one is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

(Z)-2-Methyl-4-(3-methylbenzylidene)oxazol-5(4H)-one (CAS 564441-50-5) is a high-purity analytical reference standard with the molecular formula C12H11NO2 and a molecular weight of 201.22 g/mol.

The molecular framework of (Z)-2-Methyl-4-(3-methylbenzylidene)oxazol-5(4H)-one (C12H11NO2) 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 its high hydrophobicity (logP), 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.

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), (Z)-2-Methyl-4-(3-methylbenzylidene)oxazol-5(4H)-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.
