2-Phenyl-1,3-oxazole-5-carbaldehyde CAS 92629-13-5

Description

The occurrence of 2-Phenyl-1,3-oxazole-5-carbaldehyde 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.

2-Phenyl-1,3-oxazole-5-carbaldehyde (CAS 92629-13-5), molecular formula C10H7NO2 and molecular weight 173.17 g/mol, is a CATO reference standard with documented purity and traceability.

2-Phenyl-1,3-oxazole-5-carbaldehyde (C10H7NO2) 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
