2,6-dimethyl-4-pyridinecarbonitrile 2,6-dimethylpyridine-4-carbonitrile 39965-81-6 A824825 CAS 39965-81-6

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

2,6-dimethyl-4-pyridinecarbonitrile 2,6-dimethylpyridine-4-carbonitrile 39965-81-6 A824825 (CAS 39965-81-6), molecular formula C8H14N2 and molecular weight 138.21 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C8H14N2, 2,6-dimethyl-4-pyridinecarbonitrile 2,6-dimethylpyridine-4-carbonitrile 39965-81-6 A824825 contains a nitrile group; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 138.21 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).

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.
