Chemical Structure
Description
Owing to a nitrile group, fluorine/bromine substitution, an aromatic ring system, (4-Bromo-2,3,5,6-tetrafluorophenyl)hydrazine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 259.00 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
(4-Bromo-2,3,5,6-tetrafluorophenyl)hydrazine (CAS 2797-79-7), molecular formula C6H3BrF4N2 and molecular weight 259.00 g/mol, is a CATO reference standard with documented purity and traceability.
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.
