Chemical Structure
Description
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, 2-(4'-Butyl-[1,1'-biphenyl]-4-yl)pyrimidine-5-carbonitrile is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 313.40 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).
2-(4'-Butyl-[1,1'-biphenyl]-4-yl)pyrimidine-5-carbonitrile (CAS 63617-97-0), molecular formula C21H19N3 and molecular weight 313.40 g/mol, is a CATO reference standard with documented purity and traceability.
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.
