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 1-(chlorosulfonyl)cyclohexanecarboxylate.
Methyl 1-(chlorosulfonyl)cyclohexanecarboxylate (CAS 1312138-63-8) is a high-purity analytical reference standard with the molecular formula C8H13ClO4S and a molecular weight of 240.70 g/mol.
The molecular framework of Methyl 1-(chlorosulfonyl)cyclohexanecarboxylate (C8H13ClO4S) 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.
As a certified reference material (CRM), Methyl 1-(chlorosulfonyl)cyclohexanecarboxylate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
