Chemical Structure
Description
The molecular framework of 3-Phenyl-7-(phenylsulfanyl)-2,3-dihydro-1H-inden-1-one (C21H16OS) is characterized by a steroid core, sulfur-containing functionality, a hydroxyl group, an ether linkage. 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 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).
3-Phenyl-7-(phenylsulfanyl)-2,3-dihydro-1H-inden-1-one (CAS 306976-66-9), molecular formula C21H16OS and molecular weight 316.42 g/mol, is a CATO reference standard with documented purity and traceability.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 3-Phenyl-7-(phenylsulfanyl)-2,3-dihydro-1H-inden-1-one 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.
