Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
N-(3,4-Difluorobenzyl)-5-(quinolin-8-yl)pyridin-3-amine (CAS 920529-87-9) is a high-purity analytical reference standard with the molecular formula C21H15F2N3 and a molecular weight of 347.36 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine substitution, N-(3,4-Difluorobenzyl)-5-(quinolin-8-yl)pyridin-3-amine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 347.36 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).
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.
