951892-75-4 2-Chloro-4-(3,5-difluorophenyl)-1-butene MFCD09801264 (CAS 951892-75-4) is a high-purity analytical reference standard with the molecular formula C10H9ClF2 and a molecular weight of 202.63 g/mol.
951892-75-4 2-Chloro-4-(3,5-difluorophenyl)-1-butene MFCD09801264 (C10H9ClF2) contains fluorine/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.
As a certified reference material (CRM), 951892-75-4 2-Chloro-4-(3,5-difluorophenyl)-1-butene MFCD09801264 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.
