4-Methyl-2,3-dihydrothiophene-3-sulfonyl chloride 1,1-dioxide CAS 112161-65-6

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-Methyl-2,3-dihydrothiophene-3-sulfonyl chloride 1,1-dioxide.

CATO supplies 4-Methyl-2,3-dihydrothiophene-3-sulfonyl chloride 1,1-dioxide (CAS 112161-65-6), a certified reference material (molecular formula C5H7ClO4S2, MW 230.69 g/mol) for analytical method development and quality control.

Based on its molecular formula C5H7ClO4S2, 4-Methyl-2,3-dihydrothiophene-3-sulfonyl chloride 1,1-dioxide contains a carbohydrate-derived structure, a sulfone group, chlorine substitution; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 230.69 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
