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-(Methylsulfonyl)phenyl]thiophene.
3-[4-(Methylsulfonyl)phenyl]thiophene (CAS 157259-22-8), molecular formula C11H10O2S2 and molecular weight 238.33 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C11H10O2S2, 3-[4-(Methylsulfonyl)phenyl]thiophene contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 238.33 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
