4682-03-5 Usage
General Description
A yellow crystalline solid that darkens on exposure to sunlight. Must be shipped wet with at least 40% water or water and denatured alcohol mixture. May explode due to shock, heat, flame, or friction if dry. May explode under prolonged exposure to heat or fire. Primary hazard is blast of an instantaneous explosion, not flying projectiles or fragments.
Air & Water Reactions
Dust may form an explosive mixture in air.
Reactivity Profile
Diazodinitrophenol is a diazo compound. Azo, diazo, azido compounds can detonate. The nitro groups would facilitate rapid decomposition. 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.
Health Hazard
Fire may produce irritating, corrosive and/or toxic gases.
Fire Hazard
MAY EXPLODE AND THROW FRAGMENTS 1600 meters (1 MILE) OR MORE IF FIRE REACHES CARGO.
Check Digit Verification of cas no
The CAS Registry Mumber 4682-03-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,6,8 and 2 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 4682-03:
(6*4)+(5*6)+(4*8)+(3*2)+(2*0)+(1*3)=95
95 % 10 = 5
So 4682-03-5 is a valid CAS Registry Number.

Synthesis of Polynitrodiazophenols
Atkins, Ronald L.,Wilson, William S.
, p. 2572 - 2578 (2007/10/02)
The formation of diazophenols by nitration of suitably substituted anilines and rearrangement of the nitroaromatic nitramines so formed is presented.The scope of the reaction is discussed, and a mechanism for the nitramine/diazophenol rearrangement is proposed which is consistent with 15N-labeling experiments.
