Chemical Structure

Methyl 5-[(benzenesulfonyl)methyl]furan-2-carboxylate CAS 91903-72-9 chemical structure

Description

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

CATO supplies Methyl 5-[(benzenesulfonyl)methyl]furan-2-carboxylate (CAS 91903-72-9), a certified reference material (molecular formula C13H12O5S, MW 280.30 g/mol) for analytical method development and quality control.

Based on its molecular formula C13H12O5S, Methyl 5-[(benzenesulfonyl)methyl]furan-2-carboxylate contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 280.30 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
