320-65-0 Benzene, 1-(dichloromethyl)-2-fluoro- 1-(Dichloromethyl)-2-fluorobenzene Toluene, alpha,alpha-dichloro-o-fluoro- (8CI) EINECS 206-279-7 NSC 60714 2-Fluorobenzal chloride (CAS 320-65-0), molecular formula C7H5Cl2F and molecular weight 179.02 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 320-65-0 Benzene, 1-(dichloromethyl)-2-fluoro- 1-(Dichloromethyl)-2-fluorobenzene Toluene, alpha,alpha-dichloro-o-fluoro- (8CI) EINECS 206-279-7 NSC 60714 2-Fluorobenzal chloride (C7H5Cl2F) is characterized by fluorine/chlorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).
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), 320-65-0 Benzene, 1-(dichloromethyl)-2-fluoro- 1-(Dichloromethyl)-2-fluorobenzene Toluene, alpha,alpha-dichloro-o-fluoro- (8CI) EINECS 206-279-7 NSC 60714 2-Fluorobenzal chloride 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.
