2-methyl-3,4-dinitrophenol

2-methyl-3,4-dinitrophenol is a highly toxic nitrophenol derivative with the molecular formula C7H6N2O5 and CAS number 1335-85-9. This chemical compound features a phenolic structure with two nitro groups and a methyl substituent, resulting in a molecular weight of 198.13 g/mol. It is classified as extremely hazardous due to its acute toxicity and mutagenic properties, requiring strict safety protocols for handling and use.

2-methyl-3,4-dinitrophenol is a solid organic compound with characteristic nitrophenol properties. The presence of two electron-withdrawing nitro groups significantly affects its chemical behavior, increasing acidity and reducing stability. The compound exhibits typical phenolic reactivity while the methyl group provides additional structural specificity. Due to its hazardous nature, detailed physical properties like melting point and solubility should be referenced from safety data sheets for safe handling procedures.

2-methyl-3,4-dinitrophenol is primarily used as a chemical intermediate in specialized organic synthesis and research applications. Its unique substitution pattern makes it valuable for producing specific derivatives in pharmaceutical research and fine chemical manufacturing. Due to its extreme toxicity classification (Acute Tox. 1 and 2), its use is restricted to controlled industrial environments with appropriate safety measures and qualified personnel handling hazardous materials.

2-methyl-3,4-dinitrophenol requires maximum safety precautions due to its extreme acute toxicity and skin sensitization properties. Essential PPE includes chemical-resistant gloves, full face protection, and protective clothing to prevent skin and eye contact. Work must be conducted in well-ventilated areas or fume hoods, with emergency shower and eyewash stations readily accessible. Only trained personnel should handle this substance, following strict protocols to prevent inhalation, ingestion, or dermal exposure.

2-methyl-3,4-dinitrophenol must be stored in a secure, temperature-controlled environment away from incompatible materials. Keep containers tightly sealed in a cool, dry, well-ventilated area, protected from light and moisture. Due to its extreme toxicity, storage requires restricted access with appropriate warning signs and secondary containment. Avoid contact with strong bases, reducing agents, and oxidizing materials. Regular inspection of containers for integrity is essential to prevent accidental exposure or environmental release.

Immediate action is critical due to the extreme acute toxicity of 2-methyl-3,4-dinitrophenol. For skin contact, immediately remove contaminated clothing and flush affected area with copious amounts of water for at least 15 minutes. If eye contact occurs, rinse immediately with water and seek urgent medical attention. In case of inhalation, move to fresh air immediately. For ingestion, do not induce vomiting and seek immediate medical assistance. Always contact emergency services and provide the safety data sheet to medical personnel.

2-methyl-3,4-dinitrophenol disposal requires specialized hazardous waste management due to its extreme toxicity and environmental hazard classification. The substance must be disposed of through licensed hazardous waste contractors following local and EU waste regulations. Incineration at high temperatures in approved facilities is typically required. Never dispose of this material in regular waste streams, sewers, or the environment. Maintain detailed disposal records and ensure compliance with REACH and national chemical waste regulations.

2-methyl-3,4-dinitrophenol is classified under ADR Class 6.1 (Toxic substances), Packing Group II, indicating significant transport hazards. Transportation requires UN-approved packaging, proper labeling with toxic substance markings, and accompanying transport documents. Only authorized carriers trained in hazardous materials transport should handle shipments. Vehicles must carry appropriate emergency equipment and route planning should avoid populated areas where possible. Compliance with ADR regulations and national transport requirements is mandatory for legal shipment.

2-methyl-3,4-dinitrophenol is subject to extensive regulatory oversight under multiple European frameworks. REACH registration requirements apply for manufacture and import, while CLP regulation governs classification and labeling as evidenced by its Danger signal word and multiple GHS pictograms. Although not currently listed as SVHC, its Muta. 2 classification and extreme acute toxicity subject it to strict occupational exposure limits and potential use restrictions under various national and EU chemical safety regulations.

2-methyl-3,4-dinitrophenol is available through specialized chemical distributors like OYSI, which serves the European market with technical-grade chemicals. Due to its extreme hazard classification, procurement requires verification of legitimate use, appropriate safety facilities, and qualified personnel. Suppliers must ensure proper documentation, safety data sheets, and compliance with REACH and transport regulations. Contact OYSI's technical team to discuss availability, packaging options, and regulatory requirements for this highly controlled substance.
