Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (Methylsulfonyl)methanesulfonylchloride.
(Methylsulfonyl)methanesulfonylchloride (CAS 22317-89-1) is a high-purity analytical reference standard with the molecular formula C2H5ClO4S2 and a molecular weight of 192.64 g/mol.
The molecular framework of (Methylsulfonyl)methanesulfonylchloride (C2H5ClO4S2) is characterized by a sulfone group, a carboxylic acid group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
CATO manufactures (Methylsulfonyl)methanesulfonylchloride under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
