Taylor, E. G. published the artcileDicyanotriazole. I. The conductance of dilute aqueous solutions of dicyanotriazole at 25°, Product Details of C4HN5, the publication is Canadian Journal of Research, Section B: Chemical Sciences (1942), 161-7, database is CAplus.
Previous exptl. studies of dicyanotriazole resulted in statements that the compound is an acid comparable in strength with the strong mineral acids. In the present work, measurements of the equivalent conductivity of dicyanotriazole in dilute aqueous solution give the dissociation constant of the acid as 3.378 × 10-2 at 25°; this shows it to be an acid possessing about the same strength as dichloroacetic acid. The limiting equivalent conductivity of dicyanotriazole at 25° is 384.9. The earlier work gave 397.44.
Canadian Journal of Research, Section B: Chemical Sciences published new progress about 53817-16-6. 53817-16-6 belongs to triazoles, auxiliary class Triazoles, name is 1H-1,2,3-Triazole-4,5-dicarbonitrile, and the molecular formula is C17H23BO4, Product Details of C4HN5.
