2-(Bromomethyl)-4-(difluoromethyl)-3-(trifluoromethoxy)pyridine-5-carboxaldehyde (CAS 1805280-99-2), molecular formula C9H5BrF5NO2 and molecular weight 334.04 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 2-(Bromomethyl)-4-(difluoromethyl)-3-(trifluoromethoxy)pyridine-5-carboxaldehyde (C9H5BrF5NO2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 334.04 g/mol, it falls into the moderately-high-molecular-weight range. 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.
