Description
As a certified reference material (CRM), 1-((3,4-Dichlorophenyl)thio)pentan-2-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.
1-((3,4-Dichlorophenyl)thio)pentan-2-one (CAS 1494539-88-6) is a high-purity analytical reference standard with the molecular formula C11H12Cl2OS and a molecular weight of 263.18 g/mol.
1-((3,4-Dichlorophenyl)thio)pentan-2-one (C11H12Cl2OS) contains sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
