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 methyl 3-(chlorosulfonyl)-2,2-dimethylpropanoate.
methyl 3-(chlorosulfonyl)-2,2-dimethylpropanoate (CAS 914216-23-2), molecular formula C6H11ClO4S and molecular weight 214.67 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, methyl 3-(chlorosulfonyl)-2,2-dimethylpropanoate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 214.67 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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 methyl 3-(chlorosulfonyl)-2,2-dimethylpropanoate 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.
