4-(((4-Chlorobenzyl)sulfinyl)methyl)-3,5-dimethylisoxazole CAS 303985-24-2

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-(((4-Chlorobenzyl)sulfinyl)methyl)-3,5-dimethylisoxazole.

CATO supplies 4-(((4-Chlorobenzyl)sulfinyl)methyl)-3,5-dimethylisoxazole (CAS 303985-24-2), a certified reference material (molecular formula C13H14ClNO2S, MW 283.77 g/mol) for analytical method development and quality control.

Based on its molecular formula C13H14ClNO2S, 4-(((4-Chlorobenzyl)sulfinyl)methyl)-3,5-dimethylisoxazole contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 283.77 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.
