1-methyl-2,4-dinitrobenzene

1-methyl-2,4-dinitrobenzene is an aromatic nitro compound with the molecular formula C7H6N2O4 and CAS number 121-14-2. This chemical consists of a benzene ring substituted with one methyl group and two nitro groups at specific positions. With a molecular weight of 182.13 g/mol, it belongs to the family of dinitrotoluenes and is classified as a highly hazardous substance with carcinogenic, mutagenic, and reproductive toxicity properties.

1-methyl-2,4-dinitrobenzene typically appears as a pale yellow to orange crystalline solid at room temperature. It has a characteristic aromatic odor and exhibits limited solubility in water but dissolves readily in organic solvents such as ethanol, acetone, and benzene. The compound has a relatively high melting point due to its aromatic structure and nitro substituents, making it stable under normal storage conditions but requiring careful handling due to its toxic properties.

1-methyl-2,4-dinitrobenzene serves primarily as an intermediate in the synthesis of dyes, pigments, and other organic compounds in the chemical industry. It is used in the production of explosives and propellants, and as a precursor for manufacturing various aromatic amines through reduction processes. Due to its high toxicity profile, its use is strictly regulated and limited to specialized industrial applications where proper safety measures and containment systems are in place.

Safe handling of 1-methyl-2,4-dinitrobenzene requires comprehensive personal protective equipment including respiratory protection, chemical-resistant gloves, safety goggles, and protective clothing. Work must be conducted in well-ventilated areas or under fume hoods to prevent inhalation exposure. Given its carcinogenic and mutagenic properties (Carc. 1B, Muta. 2), minimize direct contact and implement strict hygiene procedures. Regular health monitoring of workers and emergency response procedures must be established according to occupational safety regulations.

Proper storage of 1-methyl-2,4-dinitrobenzene requires a cool, dry, well-ventilated area away from heat sources, ignition sources, and incompatible materials. Store in tightly sealed original containers in a designated hazardous chemical storage area with appropriate secondary containment. Keep away from strong oxidizing agents, reducing agents, and bases. Implement access control measures due to its high toxicity profile and ensure storage areas are equipped with appropriate fire suppression systems and spill containment materials.

Immediate first aid for 1-methyl-2,4-dinitrobenzene exposure includes removing contaminated clothing and flushing affected skin with copious amounts of water for at least 15 minutes. For eye contact, rinse thoroughly with water and seek immediate medical attention. If inhaled, move the person to fresh air and provide oxygen if breathing is difficult. Never induce vomiting if ingested. Due to its acute toxicity and carcinogenic properties, seek immediate medical attention for any exposure and provide safety data sheet information to medical personnel.

Disposal of 1-methyl-2,4-dinitrobenzene must comply with local, national, and European waste regulations as hazardous waste. This substance requires specialized disposal through licensed hazardous waste management companies due to its carcinogenic and toxic properties. Incineration at high temperatures in approved facilities is typically the preferred method. Never dispose of this chemical through regular waste streams, sewage systems, or by burial. Maintain detailed records of waste disposal and ensure compliance with REACH and CLP regulations.

Transportation of 1-methyl-2,4-dinitrobenzene falls under ADR Class 6.1 (Toxic substances), Packing Group II, indicating significant transport hazards. Packaging must meet UN specification standards with appropriate labeling including GHS pictograms GHS06, GHS08, and GHS09. Transport vehicles require proper placarding and documentation including transport emergency cards. Drivers must hold ADR certification for dangerous goods transport, and shipments must comply with routing restrictions and quantity limitations as specified in European transport regulations.

Yes, 1-methyl-2,4-dinitrobenzene is subject to extensive regulatory oversight under European chemical legislation including REACH registration requirements and CLP classification obligations. Its classification as Carc. 1B, Muta. 2, and Repr. 2 subjects it to strict authorization and restriction procedures. While not currently listed as a Substance of Very High Concern (SVHC), its hazard profile may trigger future regulatory actions. Companies must comply with occupational exposure limits, environmental discharge restrictions, and comprehensive risk assessment requirements.

1-methyl-2,4-dinitrobenzene is available through specialized chemical distributors in Europe, including OYSI, which provides high-quality chemical products with comprehensive regulatory compliance documentation. Due to its hazardous nature and regulatory requirements, procurement is typically restricted to qualified industrial users with appropriate handling facilities and safety credentials. OYSI ensures full REACH compliance and provides technical support, safety documentation, and logistics solutions for this controlled substance throughout the European market.
