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-(Quinolin-2-ylmethylene)pyridin-3-amine (CAS 16722-45-5), molecular formula C15H11N3 and molecular weight 233.27 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C15H11N3, N-(Quinolin-2-ylmethylene)pyridin-3-amine contains a nitrogen-containing heterocyclic scaffold, a nitrile group; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 233.27 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
