N,N-Dibutyl-2,3,4,6,7,8,9,10-octahydropyrimido[1,2-a]azepin-10-amine CAS 106847-76-1

Description

The occurrence of N,N-Dibutyl-2,3,4,6,7,8,9,10-octahydropyrimido[1,2-a]azepin-10-amine is closely related to a nitrile group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

N,N-Dibutyl-2,3,4,6,7,8,9,10-octahydropyrimido[1,2-a]azepin-10-amine (CAS 106847-76-1), molecular formula C17H33N3 and molecular weight 279.46 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrile group, N,N-Dibutyl-2,3,4,6,7,8,9,10-octahydropyrimido[1,2-a]azepin-10-amine is typically white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 279.46 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.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

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.
