Description
Compared with other compounds in its class, the molecular weight of 263.68 g/mol gives N-(2-chlorobenzyl)-3-nitropyridin-2-amine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
N-(2-chlorobenzyl)-3-nitropyridin-2-amine (CAS 339028-02-3), molecular formula C12H10ClN3O2 and molecular weight 263.68 g/mol, is a CATO reference standard with documented purity and traceability.
N-(2-chlorobenzyl)-3-nitropyridin-2-amine (C12H10ClN3O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
