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 trans-Methyl 3-(chlorosulfonyl)cyclobutanecarboxylate.
trans-Methyl 3-(chlorosulfonyl)cyclobutanecarboxylate (CAS 1909294-41-2), molecular formula C6H9ClO4S and molecular weight 212.65 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of trans-Methyl 3-(chlorosulfonyl)cyclobutanecarboxylate (C6H9ClO4S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
