Chemical Structure
Description
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
2,6-dibromo-3-(trifluoromethyl)pyridine (CAS 55304-87-5), molecular formula C6H2Br2F3N and molecular weight 304.89 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 2,6-dibromo-3-(trifluoromethyl)pyridine (C6H2Br2F3N) contains a nitrile group, fluorine/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 304.89 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.
