Kaliszan, R. published the artcileThe relationship between the RM values and the connectivity indexes for pyrazine carbothioamide derivatives, SDS of cas: 4604-72-2, the publication is Chromatographia (1977), 10(7), 346-9, database is CAplus.
An apparent correlation was observed between the RM values obtained by using reversed-phase thin-layer chromatog. and the mol. connectivity indexes arithmetically computed for various 6-substituted derivatives of 2-pyrazinecarbothioamide. The correlation can be used to identify unknown derivatives
