Description
CATO manufactures 1-(But-3-en-1-yl)-3,5-difluorobenzene 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.
1-(But-3-en-1-yl)-3,5-difluorobenzene (CAS 225240-58-4) is a high-purity analytical reference standard with the molecular formula C10H10F2 and a molecular weight of 168.18 g/mol.
1-(But-3-en-1-yl)-3,5-difluorobenzene (C10H10F2) contains fluorine 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. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
