Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 262.71 g/mol gives Ethyl 4-[(chlorosulfonyl)methyl]benzoate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Ethyl 4-[(chlorosulfonyl)methyl]benzoate (CAS 446847-82-1), a certified reference material (molecular formula C10H11ClO4S, MW 262.71 g/mol) for analytical method development and quality control.
The molecular framework of Ethyl 4-[(chlorosulfonyl)methyl]benzoate (C10H11ClO4S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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), Ethyl 4-[(chlorosulfonyl)methyl]benzoate 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.
