Chemical Structure
Description
3-((4-Chlorophenyl)thio)-1-(naphthalen-2-yl)propan-1-one (CAS 882073-33-8), molecular formula C19H15ClOS and molecular weight 326.84 g/mol, is a CATO reference standard with documented purity and traceability.
3-((4-Chlorophenyl)thio)-1-(naphthalen-2-yl)propan-1-one (C19H15ClOS) 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
CATO manufactures 3-((4-Chlorophenyl)thio)-1-(naphthalen-2-yl)propan-1-one under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
