N1,N1-Bis(pyridin-2-ylmethyl)ethane-1,2-diamine CAS 189440-33-3

Description

The occurrence of N1,N1-Bis(pyridin-2-ylmethyl)ethane-1,2-diamine is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

N1,N1-Bis(pyridin-2-ylmethyl)ethane-1,2-diamine (CAS 189440-33-3) is a high-purity analytical reference standard with the molecular formula C14H18N4 and a molecular weight of 242.32 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, N1,N1-Bis(pyridin-2-ylmethyl)ethane-1,2-diamine is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 242.32 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
