2-methyl-3,4-dinitrophenol

2-methyl-3,4-dinitrophenol is an organic chemical compound with the molecular formula C7H6N2O5 and CAS number 1335-85-9. This nitrophenol derivative has a molecular weight of 198.13 g/mol and belongs to the family of substituted phenols. It is characterized by the presence of two nitro groups and one methyl group attached to a phenol ring, making it a highly hazardous substance classified with multiple danger categories including acute toxicity and mutagenicity.

2-methyl-3,4-dinitrophenol is typically a solid crystalline substance at room temperature with a characteristic yellow to orange color. The compound has a molecular weight of 198.13 g/mol and contains both hydrophilic (phenolic hydroxyl, nitro groups) and lipophilic (methyl group) functional groups. Its nitro substituents make it highly polar and potentially explosive under certain conditions. The presence of multiple electron-withdrawing groups significantly affects its chemical reactivity and stability properties.

2-methyl-3,4-dinitrophenol is primarily used as a chemical intermediate in organic synthesis and pharmaceutical manufacturing. It serves as a precursor for the production of various fine chemicals, dyes, and specialized pharmaceutical compounds. The compound may also be utilized in analytical chemistry as a reagent or standard. Due to its high toxicity profile and strict regulatory controls, its applications are limited to specialized industrial processes requiring appropriate safety measures and trained personnel.

2-methyl-3,4-dinitrophenol requires strict safety protocols due to its acute toxicity and mutagenic properties. Essential personal protective equipment includes chemical-resistant gloves, safety goggles, full-face respirator, and protective clothing. Work must be conducted in well-ventilated areas or under fume hoods to prevent inhalation exposure. Avoid skin and eye contact completely, and ensure emergency shower and eyewash stations are readily accessible. Only trained personnel should handle this substance following established safety procedures.

2-methyl-3,4-dinitrophenol must be stored in a cool, dry, well-ventilated area away from heat sources, direct sunlight, and incompatible materials. Use original containers or approved secondary containment made of compatible materials. Store separately from reducing agents, strong bases, and organic solvents to prevent dangerous reactions. Access should be restricted to authorized personnel only, and storage areas must be clearly labeled with appropriate hazard warnings and equipped with spill containment measures.

2-methyl-3,4-dinitrophenol exposure requires immediate emergency response due to its high toxicity. For skin contact, immediately remove contaminated clothing and flush with copious amounts of water for at least 15 minutes. In case of eye contact, rinse immediately with water for at least 15 minutes and seek medical attention. If inhaled, move to fresh air immediately. For ingestion, do not induce vomiting and seek immediate medical attention. Always contact poison control or emergency services after any exposure incident.

2-methyl-3,4-dinitrophenol disposal must comply with local, national, and European waste regulations as hazardous chemical waste. The substance cannot be disposed of through normal waste streams due to its toxicity and environmental hazard classification. Disposal must be performed by licensed hazardous waste contractors through approved methods such as high-temperature incineration in specialized facilities. Containers must be properly labeled, and waste documentation must accompany all disposal activities according to regulatory requirements.

2-methyl-3,4-dinitrophenol is classified as ADR Class 6.1 (Toxic substances), Packing Group II, requiring specialized transport procedures. Packages must meet UN specification requirements and display appropriate hazard labels and markings. Transport vehicles must carry emergency response information and appropriate safety equipment. Drivers require ADR certification for dangerous goods transport. Shipping documentation must include proper shipping names, hazard classifications, and emergency contact information according to international dangerous goods regulations.

2-methyl-3,4-dinitrophenol is subject to comprehensive European chemical regulations including REACH registration requirements and CLP classification obligations. The substance's multiple hazard classifications (mutagenicity, acute toxicity, skin sensitization) trigger specific labeling, safety data sheet, and risk assessment requirements. Users must comply with occupational exposure limits, worker protection measures, and environmental discharge restrictions. Import, use, and distribution may require permits or notifications depending on quantities and applications within EU member states.
