methyl 5-(chlorosulfonyl)-2-fluoro-4-methoxybenzoate CAS 2060056-99-5

Description

The occurrence of methyl 5-(chlorosulfonyl)-2-fluoro-4-methoxybenzoate is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies methyl 5-(chlorosulfonyl)-2-fluoro-4-methoxybenzoate (CAS 2060056-99-5), a certified reference material (molecular formula C9H8ClFO5S, MW 282.67 g/mol) for analytical method development and quality control.

The molecular framework of methyl 5-(chlorosulfonyl)-2-fluoro-4-methoxybenzoate (C9H8ClFO5S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
