Chemical Structure
Description
3-Bromo-5-chloro-2-fluoro-4-trifluoromethylpyridine (CAS 1349718-20-2) is a high-purity analytical reference standard with the molecular formula C6HBrClF4N and a molecular weight of 278.43 g/mol.
Structurally, 3-Bromo-5-chloro-2-fluoro-4-trifluoromethylpyridine (C6HBrClF4N) contains a nitrile group, fluorine/chlorine/bromine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 278.43 g/mol, it falls into the medium-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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
