Chemical Structure
Description
CATO supplies 4-Chloro-3-(5,7-dimethylbenzo[d]oxazol-2-yl)aniline (CAS 292644-39-4), a certified reference material (molecular formula C15H13ClN2O, MW 272.73 g/mol) for analytical method development and quality control.
Based on its molecular formula C15H13ClN2O, 4-Chloro-3-(5,7-dimethylbenzo[d]oxazol-2-yl)aniline contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 272.73 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
