Guanazole

Diazo-5-phenyl-1,2,4-triazole reacted with methylamine to give the corresponding triazene (83JHC1629). Triazeno polymer 240 was formed by a self-coupling reaction of the diazotriazole obtained from guanazole... 

Guanazole. Same as 3,5-Diamino-asym-tri-azole, described in Vol 5, p D1148-L R. 

Aryl guanazoles are reported to react with 1,2-diformylhydrazine to give products of type (591) (52G735). 

Diamino-a-s-triazole, Aminoaminotriazole or Guanazole (called 3.5-Diimino-L2u4-triazolidin Urazol-diimid 3°5-Diamino-l02.4-triazol or Guanazol in Ger),... 

Stolle Dietrich (Ref 2) report a Dinitrate compd, pale-yel crysts, mp exploding when heated rapidly at 145° was prepd by treating a soln of guanazole in 2NHC1 with 65% HNO3... 

C2HN504 mw 159.08 N 44.03% OB to C02 —5.03% yel hygr solid mp, flashes when dropped on a hot plate. Sol in alcohols, eth and w. Prepn is by the dropwise addn of an excess of nitric acid to a cold soln of guanazole and cupric nitrate in 40% aq Na nitrate. The product is pptd as the Ag salt which is recovered and decompd to the free acid by treatment with... 

N 44.9%, crysts, mp 217° with vigorous de-compn dissolves in w, giving a strongly acidic soln, nearly insol in ale and insol in eth. Was prepd by adding the dinitroso deriv of guanazole to a soln of SnCl2 in HCl... 

Two series of dyes are derived from 3,5-diamino-l,2,4-triazole [1455-77-2, also known as guanazole. The monoazo dyes form red diazadimethine dyes (e.g., 35) after alkylation [88],... 

The disazo dyes formed from guanazole produce reddish blue diazadimethine dyes on alkylation [89], e.g., 36. 

Mono- and bis-diazacyanine dyes are derived from guanazole. Whereas the mono diazacyanine dyes dye polyacrylonitrile reddish yellow shades [105], the bis-diazacyanines [106] produce red dyeings, e.g. 45. 

Amino-5-cloro-l,2,4-triazole is obtained from guanazol (3,5-dinitro-l,2,4-tri-azole) by the direction diazotiation in hydrochloric acid (a), but at first it more rationally is the guanazol mononitrosation with treatment followed by heated HC1 (b). 

A few trivial names for 1,2,4-triazoles are in common use 3,5-dioxo-l,2,4-triazolidines (5) are called urazoles, and the corresponding 3,5-diamino compounds (6) guanazoles. 

Acylation of guanazole (6) is complex (60Rtc836) although acetylation on N-1 or N-2 has not been rigorously established, the assignments are in agreement with later findings...
