Ethyl 5-(chlorosulfonyl)furan-2-carboxylate CAS 87299-59-0

Description

The occurrence of Ethyl 5-(chlorosulfonyl)furan-2-carboxylate is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Ethyl 5-(chlorosulfonyl)furan-2-carboxylate (CAS 87299-59-0), a certified reference material (molecular formula C7H7ClO5S, MW 238.65 g/mol) for analytical method development and quality control.

The molecular framework of Ethyl 5-(chlorosulfonyl)furan-2-carboxylate (C7H7ClO5S) 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 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
