Structure of 2,4,6-Trinitro-m-cresol (CAS NO.602-99-3):
                  
IUPAC Name of 2,4,6-Trinitro-m-cresol (CAS NO.602-99-3): 3-Methyl-2,4,6-trinitrophenol

A poison. A severe explosion hazard when shocked or exposed to heat. Explodes when heated above 150°C. Trinitrocresol is not as powerful a high explosive as TNT or picric acid. Can react vigorously with oxidizing materials. When heated to decomposition it emits highly toxic fumes of NO_x and explodes. See also NITRO COMPOUNDS of AROMATIC HYDROCARBONS and EXPLOSIVES, HIGH.
Hazard Codes: E,Xn
Risk Statements: 2-4-20/21/22 
R2:Risk of explosion by shock, friction, fire or other source of ignition.
R4 :Forms very sensitive explosive metallic compounds. 
R20/21/22:Harmful by inhalation, in contact with skin and if swallowed.
Safety Statements: 35 
S35:This material and its container must be disposed of in a safe way.

 2,4,6-Trinitro-m-cresol ,its cas register number is 602-99-3. It also can be called 2,4,6-Trinitro-3-methylphenol ; 3-Methyl-2,4,6-trinitro-phenol ; and Picric acid, 3-methyl- . 2,4,6-Trinitro-m-cresol (CAS NO.602-99-3) is sensitive to heat, and is a nitroaryl derivative. Nitroaryls range from slight to strong oxidizing agents. If mixed with reducing agents, including hydrides, sulfides and nitrides, they may begin a vigorous reaction that culminates in a detonation. Under prolonged exposure to fire or heat the containers may explode violently.
