3-(4-tert-Butylphenyl)-5-(2-methanesulfinylphenyl)-1,2,4-oxadiazole CAS 339099-77-3

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-(4-tert-Butylphenyl)-5-(2-methanesulfinylphenyl)-1,2,4-oxadiazole.

3-(4-tert-Butylphenyl)-5-(2-methanesulfinylphenyl)-1,2,4-oxadiazole (CAS 339099-77-3) is a high-purity analytical reference standard with the molecular formula C19H20N2O2S and a molecular weight of 340.44 g/mol.

Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 3-(4-tert-Butylphenyl)-5-(2-methanesulfinylphenyl)-1,2,4-oxadiazole is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 340.44 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
