Reactivity Profile
2'-METHYL-4-DIMETHYLAMINOAZOBENZENE is an azo compound. Azo, diazo, azido compounds can detonate. This applies in particular to organic azides that have been sensitized by the addition of metal salts or strong acids. Toxic gases are formed by mixing materials of this class with acids, aldehydes, amides, carbamates, cyanides, inorganic fluorides, halogenated organics, isocyanates, ketones, metals, nitrides, peroxides, phenols, epoxides, acyl halides, and strong oxidizing or reducing agents. Flammable gases are formed by mixing materials in this group with alkali metals. Explosive combination can occur with strong oxidizing agents, metal salts, peroxides, and sulfides.
Air and Water ReactionsDust can be explosive when suspended in air at specific concentrations. Insoluble in water.

Pharmacology
Absorption, Distribution and Excretion
THE LEVEL OF BINDING OF TRITIATED PARA-DIMETHYLAMINOAZOBENZENE & THE NON- CARCINOGENIC 2-METHYL-4-DIMETHYLAMINOAZOBENZENE TO DIFFERENT CELL FRACTIONS OF RAT LIVER & SPLEEN FOLLOWING SINGLE ORAL ADMIN WERE SIMILAR, EXCEPT THAT MORE DNA WAS BOUND TO THE CARCINOGEN BETWEEN 4 & 8 HR AFTER ADMIN. ...BINDING OF CARCINOGENIC 3'-METHYL-4-DIMETHYLAMINOAZOBENZENE TO DNA WAS 6 TIMES GREATER THAN THAT OF 2-METHYL-4-DIMETHYLAMINOAZOBENZENE. WHEN (14)C-LABELED PARA-DIMETHYLAMINOAZOBENZENE OR 2-METHYL-4-DIMETHYLAMINOAZOBENZENE WERE GIVEN CONTINUOUSLY TO RATS IN DIET, BINDING OF 2-METHYL-4-DIMETHYLAMINOAZOBENZENE TO LIVER PROTEIN WAS SLIGHTLY HIGHER THAN THAT OF CARCINOGENIC COMPD. PARA-DIMETHYLAMINOAZOBENZENE, WAS HOWEVER, BOUND MUCH MORE TO DNA OF LIVER THAN WAS NON-CARCINOGENIC ANALOGUE.
Applications
