Chemical Structure

3-Fluorobenzal Chloride CAS 402-64-2 chemical structure

Description

3-Fluorobenzal Chloride (C7H5Cl2F) contains fluorine/chlorine 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).

3-Fluorobenzal Chloride (CAS 402-64-2) is a high-purity analytical reference standard with the molecular formula C7H5Cl2F and a molecular weight of 179.02 g/mol.

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.

As a certified reference material (CRM), 3-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.
