Chemical Structure
Description
1-{[1,1'-biphenyl]-4-yl}-3-[(4-chlorophenyl)sulfanyl]propan-1-one (CAS 882748-91-6) is a high-purity analytical reference standard with the molecular formula C21H17ClOS and a molecular weight of 352.88 g/mol.
1-{[1,1'-biphenyl]-4-yl}-3-[(4-chlorophenyl)sulfanyl]propan-1-one (C21H17ClOS) contains a steroid core, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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), 1-{[1,1'-biphenyl]-4-yl}-3-[(4-chlorophenyl)sulfanyl]propan-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.
