(2,2,5,5-Tetramethyloxolan-3-yl)methanesulfonyl chloride CAS 2090313-43-0

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (2,2,5,5-Tetramethyloxolan-3-yl)methanesulfonyl chloride.

(2,2,5,5-Tetramethyloxolan-3-yl)methanesulfonyl chloride (CAS 2090313-43-0) is a high-purity analytical reference standard with the molecular formula C9H17ClO3S and a molecular weight of 240.75 g/mol.

Based on its molecular formula C9H17ClO3S, (2,2,5,5-Tetramethyloxolan-3-yl)methanesulfonyl chloride contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 240.75 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.
