1-methyl-2,4-dinitrobenzene

1-methyl-2,4-dinitrobenzene is an aromatic organic compound with the molecular formula C7H6N2O4 and CAS number 121-14-2. This chemical belongs to the dinitrotoluene family and features 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 is classified as a highly hazardous substance due to its carcinogenic, mutagenic, and reproductive toxicity properties.

1-methyl-2,4-dinitrobenzene typically appears as a yellow to orange crystalline solid at room temperature. The compound has limited water solubility but dissolves well in organic solvents such as ethanol, acetone, and benzene. It exhibits a characteristic aromatic odor and has a relatively high melting point due to its aromatic structure and nitro substituents. The presence of electron-withdrawing nitro groups significantly affects its chemical reactivity and physical properties.

1-methyl-2,4-dinitrobenzene serves primarily as an intermediate in chemical synthesis, particularly in the production of dyes, pigments, and other aromatic compounds. It is used in the manufacture of explosives and as a precursor for various nitroaromatic derivatives. The compound also finds application in research laboratories for synthetic organic chemistry. Due to its high toxicity, its use is strictly regulated and limited to industrial processes with appropriate safety measures.

1-methyl-2,4-dinitrobenzene requires extreme caution during handling 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 a well-ventilated area or under fume hood conditions. Avoid skin contact, inhalation, and ingestion at all costs. Personnel should be trained in hazardous material handling procedures and emergency response protocols before working with this substance.

1-methyl-2,4-dinitrobenzene must be stored in a cool, dry, well-ventilated area away from heat sources and incompatible materials. The substance should be kept in tightly sealed, chemically resistant containers, preferably in a designated hazardous materials storage area. Avoid storage near oxidizing agents, reducing agents, and strong acids. Temperature control is important to prevent decomposition. Access should be restricted to authorized personnel only, with appropriate safety signage and inventory controls.

Immediate action is required upon contact with 1-methyl-2,4-dinitrobenzene. For skin contact, remove contaminated clothing and wash thoroughly with soap and water for at least 15 minutes. If inhaled, move to fresh air immediately. For eye contact, flush with clean water for at least 15 minutes. In case of ingestion, do not induce vomiting and seek immediate medical attention. Always inform medical personnel about the specific chemical involved and provide safety data sheet information.

1-methyl-2,4-dinitrobenzene disposal must comply with local, national, and international hazardous waste regulations. The substance cannot be disposed of through normal waste streams due to its toxic and potentially carcinogenic properties. Licensed hazardous waste disposal companies must handle the waste, typically through high-temperature incineration or other approved treatment methods. All disposal activities must be documented and tracked according to regulatory requirements. Empty containers also require special handling as hazardous waste.

1-methyl-2,4-dinitrobenzene is classified as ADR Class 6.1 (toxic substances), Packing Group II, indicating significant transport hazards. Transportation requires compliance with dangerous goods regulations including proper packaging, labeling with GHS pictograms (GHS06, GHS08, GHS09), and documentation. Vehicles must carry appropriate emergency equipment and drivers need hazardous materials certification. The substance must be segregated from incompatible materials during transport and emergency response information must be readily available.

1-methyl-2,4-dinitrobenzene is subject to extensive regulatory oversight under multiple frameworks including REACH registration requirements, CLP classification as Category 1B carcinogen, and various national chemical control laws. The substance requires proper classification with danger signal word and multiple hazard statements covering carcinogenicity, mutagenicity, and reproductive toxicity. Users must implement risk management measures, provide safety training, and maintain detailed exposure records. Import/export may require special permits depending on jurisdiction.

1-methyl-2,4-dinitrobenzene is available through specialized chemical distributors in Europe, including OYSI, which serves as a reliable supplier for industrial and research applications. Due to the substance's hazardous classification, purchases typically require verification of legitimate use, appropriate handling facilities, and compliance with regulatory requirements. Buyers must demonstrate proper safety infrastructure and trained personnel. Contact OYSI for availability, technical specifications, and regulatory documentation to ensure compliant procurement of this controlled substance.
