2-methyl-1,3-dinitrobenzene

2-methyl-1,3-dinitrobenzene is an aromatic nitro compound with the molecular formula C7H6N2O4 and CAS number 606-20-2. This chemical consists of a benzene ring substituted with a methyl group and two nitro groups in positions 1 and 3. With a molecular weight of 182.13 g/mol, it belongs to the class of dinitrotoluene isomers and is classified as a highly hazardous substance with carcinogenic, mutagenic, and reproductive toxicity properties.

2-methyl-1,3-dinitrobenzene is typically a crystalline solid at room temperature with a characteristic aromatic odor. As a nitroaromatic compound, it exhibits limited water solubility but dissolves well in organic solvents such as alcohols and ketones. The presence of two electron-withdrawing nitro groups significantly affects its chemical reactivity and stability. Its melting point and other specific physical properties depend on purity and crystalline form.

2-methyl-1,3-dinitrobenzene is primarily used as an intermediate in organic synthesis and chemical manufacturing processes. It serves as a precursor for the production of various dyes, pigments, and pharmaceutical compounds. In industrial applications, it may be utilized in the synthesis of specialized chemicals and as a building block for more complex aromatic compounds. Its use is typically restricted to professional industrial settings due to its hazardous classification.

2-methyl-1,3-dinitrobenzene requires strict safety measures due to its carcinogenic and toxic properties. Essential personal protective equipment includes chemical-resistant gloves, safety goggles, and respiratory protection. Work must be conducted in well-ventilated areas or under fume hoods to prevent inhalation exposure. Skin contact must be avoided at all costs, and contaminated clothing should be removed immediately. Only trained personnel should handle this substance following established safety protocols.

2-methyl-1,3-dinitrobenzene must be stored in a cool, dry, well-ventilated area away from heat sources and incompatible materials. Storage containers should be tightly sealed and made of compatible materials to prevent contamination. The storage area should be secured and accessible only to authorized personnel due to the substance's hazardous nature. Regular inspection of containers for signs of deterioration or leakage is essential for safe storage management.

Immediate action is crucial in case of contact with 2-methyl-1,3-dinitrobenzene. For skin contact, remove contaminated clothing and wash the affected area thoroughly with soap and water for at least 15 minutes. In case of eye contact, rinse immediately with clean water for 15 minutes. If inhaled, move the person to fresh air immediately. Seek medical attention promptly in all cases of exposure, informing medical personnel about the specific chemical involved.

2-methyl-1,3-dinitrobenzene must be disposed of as hazardous waste according to local and national environmental regulations. Disposal should only be carried out by licensed waste management companies specialized in handling toxic chemicals. The substance cannot be disposed of in regular waste streams or sewage systems due to its environmental and health hazards. Proper documentation and waste tracking procedures must be followed throughout the disposal process.

2-methyl-1,3-dinitrobenzene is classified under ADR Class 6.1 (Toxic substances) Packing Group II, indicating significant transport hazards. Transportation requires proper packaging, labeling with GHS06 and GHS08 pictograms, and compliance with dangerous goods regulations. Vehicles must carry appropriate safety equipment and documentation. Only certified carriers experienced in handling toxic chemicals should transport this substance, following all applicable national and international transport regulations for dangerous goods.

2-methyl-1,3-dinitrobenzene is subject to extensive regulatory oversight under REACH and CLP regulations in Europe. Its classification as Carcinogenic 1B, Mutagenic 2, and Reproductive toxicant 2 triggers strict handling and use restrictions. Companies must comply with registration requirements, safety data sheet provisions, and workplace exposure limits. Special authorization may be required for certain uses, and regular monitoring of occupational exposure is mandatory in industrial settings.

2-methyl-1,3-dinitrobenzene is available through specialized chemical distributors like OYSI, which serves the European market with technical chemicals. Due to its hazardous classification, purchase is typically restricted to qualified industrial users with proper handling facilities and safety protocols. Buyers must provide appropriate documentation and comply with regulatory requirements. OYSI can provide technical support and safety documentation to ensure compliant procurement and use of this controlled substance.
