Air & Water Reactions
Azo dyes can be explosive when suspended in air at specific concentrations. Insoluble in water.
Reactivity Profile
Pigment Red 23 is sensitive to light and may be sensitive to heat. Pigment Red 23 is incompatible with strong oxidizing agents. . Pigment Red 23 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.

Check Digit Verification of cas no
The CAS Registry Mumber 6471-49-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,4,7 and 1 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 6471-49:
(6*6)+(5*4)+(4*7)+(3*1)+(2*4)+(1*9)=104
104 % 10 = 4
So 6471-49-4 is a valid CAS Registry Number.
