Chemical Structure
Description
3-({[4-(propan-2-yl)benzene]sulfonyl}methyl)furan-2-carboxylic acid (CAS 1094269-20-1), molecular formula C15H16O5S and molecular weight 308.35 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-({[4-(propan-2-yl)benzene]sulfonyl}methyl)furan-2-carboxylic acid (C15H16O5S) is characterized by a flavonoid core, a sulfone group, a hydroxyl group, an ether linkage. 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
