2-(1,1-Dioxo-2,3-dihydro-1lambda6-benzothiophen-3-yl)acetic acid (CAS 130105-46-3), molecular formula C10H10O4S and molecular weight 226.25 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-(1,1-Dioxo-2,3-dihydro-1lambda6-benzothiophen-3-yl)acetic acid (C10H10O4S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
As a certified reference material (CRM), 2-(1,1-Dioxo-2,3-dihydro-1lambda6-benzothiophen-3-yl)acetic acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
