(5-Phenyl-1,2-oxazol-3-yl)methyl 3-chlorobenzoate CAS 343374-53-8

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (5-Phenyl-1,2-oxazol-3-yl)methyl 3-chlorobenzoate.

CATO supplies (5-Phenyl-1,2-oxazol-3-yl)methyl 3-chlorobenzoate (CAS 343374-53-8), a certified reference material (molecular formula C17H12ClNO3, MW 313.74 g/mol) for analytical method development and quality control.

(5-Phenyl-1,2-oxazol-3-yl)methyl 3-chlorobenzoate (C17H12ClNO3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, 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 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.
