Zakirov, N. S. et al. published their research in Zhurnal Analiticheskoi Khimii in 1987 | CAS: 7528-78-1

3,3′,3”-Nitrilotripropanenitrile (cas: 7528-78-1) belongs to nitriles. Nitrile compounds can be prepared by the incorporation of a cyanide source through C–C bond formation or by dehydration of primary carboxamides. Some nitriles are manufactured by heating carboxylic acids with ammonia in the presence of catalysts. This process is used to make nitriles from natural fats and oils, the products being used as softening agents in synthetic rubbers, plastics, and textiles and for making amines.Formula: C9H12N4

Use of the least squares method for estimating the sorption capability of cyano-group-containing phases in gas chromatography was written by Zakirov, N. S.. And the article was included in Zhurnal Analiticheskoi Khimii in 1987.Formula: C9H12N4 This article mentions the following:

The least squares method was used for quant. estimation of the sorption capability of cyano-group containing stationary phases in gas chromatog. separation of alcs., nitriles, and hydrocarbons. The method can be used for selection and optimization of stationary phases with respect to analyte chain length. In the experiment, the researchers used many compounds, for example, 3,3′,3”-Nitrilotripropanenitrile (cas: 7528-78-1Formula: C9H12N4).
