Chemical Structure

2-Cyclopropylethanesulfonyl Chloride CAS 1196155-54-0 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 2-Cyclopropylethanesulfonyl Chloride.

2-Cyclopropylethanesulfonyl Chloride (CAS 1196155-54-0) is a high-purity analytical reference standard with the molecular formula C5H9ClO2S and a molecular weight of 168.64 g/mol.

Structurally, 2-Cyclopropylethanesulfonyl Chloride (C5H9ClO2S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 1.0, corresponding to approximately 1 ring(s) or double-bond equivalent(s). With a molecular weight of 168.64 g/mol, it falls into the medium-molecular-weight range. 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 2-Cyclopropylethanesulfonyl Chloride 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.
