Chemical Structure

2,2'-Azobis(2-methylpropionitrile) CAS 78-67-1 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 164.21 g/mol gives 2,2'-Azobis(2-methylpropionitrile) distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 2,2'-Azobis(2-methylpropionitrile) (CAS 78-67-1), a certified reference material (molecular formula C8H12N4, MW 164.21 g/mol) for analytical method development and quality control.

Based on its molecular formula C8H12N4, 2,2'-Azobis(2-methylpropionitrile) contains a nitrogen-containing heterocyclic scaffold, a nitrile group; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 164.21 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
