Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
3-(3,5-Dichlorophenyl)-2-methyl-1-propene (CAS 69278-44-0), molecular formula C10H10Cl2 and molecular weight 201.09 g/mol, is a CATO reference standard with documented purity and traceability.
3-(3,5-Dichlorophenyl)-2-methyl-1-propene (C10H10Cl2) contains 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.
As a certified reference material (CRM), 3-(3,5-Dichlorophenyl)-2-methyl-1-propene 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.
