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.
6-Fluoro-4-formylpicolinonitrile (CAS 1288990-67-9) is a high-purity analytical reference standard with the molecular formula C7H3FN2O and a molecular weight of 150.11 g/mol.
Owing to an amide group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system, 6-Fluoro-4-formylpicolinonitrile is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 150.11 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).
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.
