7227-91-0 Usage
Air & Water Reactions
Insoluble in water.
Reactivity Profile
3,3-dimethyl-1-phenyltriazene neutralizes acids in exothermic reactions to form salts plus water. May be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen may be generated in combination with strong reducing agents, such as hydrides.
Safety Profile
Poison by ingestion and
intraperitoneal routes. Questionable
carcinogen with experimental carcinogenic
and tumorigenic data. Experimental
teratogenic effects. Human mutation data
reported. Decomposes explosively on
attempted distillation at atmospheric
pressure. When heated to decomposition it
emits toxic fumes of NOx
Check Digit Verification of cas no
The CAS Registry Mumber 7227-91-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,2,2 and 7 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 7227-91:
(6*7)+(5*2)+(4*2)+(3*7)+(2*9)+(1*1)=100
100 % 10 = 0
So 7227-91-0 is a valid CAS Registry Number.

The reactions of 1-aryl-2-bromodiazene 1-oxides with HCl in nonaqueous media give aryldiazonium chlorides, while 1,3,3-substituted triazenes-1 are formed in the reactions with secondary amines. Using 2-(15N) label, it was shown that the aryl group does not migrate in these reactions.
