Chemical Structure
Description
3-Bromo-5-fluoro-2-(3-(trifluoromethyl)-3H-diazirin-3-yl)pyridine (CAS 2231675-76-4) is a high-purity analytical reference standard with the molecular formula C7H2BrF4N3 and a molecular weight of 284.01 g/mol.
Owing to a nitrile group, fluorine/bromine substitution, an aromatic ring system, 3-Bromo-5-fluoro-2-(3-(trifluoromethyl)-3H-diazirin-3-yl)pyridine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 284.01 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
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.
