3-phenyl-2,3-dihydro-1$l^{6}-thiophene-1,1-dione CAS 42925-28-0

Description

The occurrence of 3-phenyl-2,3-dihydro-1$l^{6}-thiophene-1,1-dione 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.

3-phenyl-2,3-dihydro-1$l^{6}-thiophene-1,1-dione (CAS 42925-28-0), molecular formula C10H10O2S and molecular weight 194.25 g/mol, is a CATO reference standard with documented purity and traceability.

3-phenyl-2,3-dihydro-1$l^{6}-thiophene-1,1-dione (C10H10O2S) 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.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), 3-phenyl-2,3-dihydro-1$l^{6}-thiophene-1,1-dione 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.
