Chemical Structure
Description
2-{[(thiophen-3-yl)methyl]sulfanyl}benzoic acid (CAS 62688-29-3) is a high-purity analytical reference standard with the molecular formula C12H10O2S2 and a molecular weight of 250.34 g/mol.
2-{[(thiophen-3-yl)methyl]sulfanyl}benzoic acid (C12H10O2S2) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
