Description
CATO manufactures 1,5-bis(3,4-dichlorophenyl)penta-1,4-dien-3-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.
CATO supplies 1,5-bis(3,4-dichlorophenyl)penta-1,4-dien-3-one (CAS 42160-05-4), a certified reference material (molecular formula C17H10Cl4O, MW 372.07 g/mol) for analytical method development and quality control.
1,5-bis(3,4-dichlorophenyl)penta-1,4-dien-3-one (C17H10Cl4O) contains a steroid core, 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.
