Description
CATO manufactures 1-(Difluoromethyl)-4-vinylbenzene 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-(Difluoromethyl)-4-vinylbenzene (CAS 1548183-93-2), molecular formula C9H8F2 and molecular weight 154.16 g/mol, is a CATO reference standard with documented purity and traceability.
1-(Difluoromethyl)-4-vinylbenzene (C9H8F2) contains fluorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
