Chemical Structure
Description
The occurrence of 1-Pyrazin-2-yl-[1,4]diazepane, 97% 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.
CATO supplies 1-Pyrazin-2-yl-[1,4]diazepane, 97% (CAS 502133-53-1), a certified reference material (molecular formula C9H14N4, MW 178.23 g/mol) for analytical method development and quality control.
Based on its molecular formula C9H14N4, 1-Pyrazin-2-yl-[1,4]diazepane, 97% contains a nitrogen-containing heterocyclic scaffold, a nitrile group; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 178.23 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.
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.
