1,2,3,4-tetranitro-9H-carbazole

1,2,3,4-tetranitro-9H-carbazole is a highly nitrated organic compound with the molecular formula C12H5N5O8 and CAS number 6202-15-9. This carbazole derivative contains four nitro groups attached to the carbazole ring structure, giving it a molecular weight of 347.2 g/mol. It is classified as an explosive substance (Expl. 1.1) and exhibits acute toxicity properties, making it a hazardous chemical requiring specialized handling and safety measures.

1,2,3,4-tetranitro-9H-carbazole is a solid crystalline compound at room temperature due to its aromatic structure and multiple nitro substituents. The presence of four electron-withdrawing nitro groups significantly affects its physical properties, likely resulting in low solubility in water but potential solubility in organic solvents. The compound's high degree of nitration contributes to its explosive nature and chemical instability under certain conditions.

1,2,3,4-tetranitro-9H-carbazole is primarily used in specialized research applications and potentially in explosive formulations due to its Expl. 1.1 classification. Its applications are typically limited to controlled laboratory environments for chemical research, analytical studies, or as a reference standard. Given its hazardous properties, this compound is not suitable for general industrial use and requires specialized expertise and facilities for safe handling and application.

1,2,3,4-tetranitro-9H-carbazole requires extreme caution during handling due to its explosive and toxic properties. Personnel must wear appropriate PPE including safety goggles, protective gloves, and protective clothing. Work should be conducted in well-ventilated areas or under fume hoods, away from heat sources, sparks, and friction. Only trained personnel familiar with explosive materials should handle this substance, following strict safety protocols and emergency procedures.

1,2,3,4-tetranitro-9H-carbazole must be stored in a cool, dry place away from heat, direct sunlight, and ignition sources due to its explosive nature. The storage area should be well-ventilated and separated from incompatible materials such as strong oxidizers, reducing agents, and organic materials. Containers should be properly labeled and stored in accordance with local regulations for explosive substances, with appropriate security measures and access restrictions.

Immediate action is required upon contact with 1,2,3,4-tetranitro-9H-carbazole due to its acute toxicity. For skin contact, remove contaminated clothing and wash thoroughly with soap and water. In case of eye contact, rinse immediately with plenty of water for at least 15 minutes. If inhaled, move to fresh air immediately. For ingestion, do not induce vomiting and seek immediate medical attention. Contact emergency services if symptoms develop or exposure is significant.

1,2,3,4-tetranitro-9H-carbazole disposal requires specialized hazardous waste management due to its explosive and toxic properties. The substance must not be disposed of in regular waste streams or sewers. Contact licensed hazardous waste disposal companies experienced in handling explosive materials. Disposal must comply with local, national, and EU regulations for explosive and toxic substances. Small quantities may require controlled incineration or other approved destruction methods under professional supervision.

1,2,3,4-tetranitro-9H-carbazole transport requires compliance with ADR regulations for dangerous goods due to its explosive classification. Specialized packaging, labeling, and documentation are mandatory for road transport. Only authorized carriers with proper permits and training for explosive materials can transport this substance. Vehicle requirements, route restrictions, and emergency procedures must be followed according to international dangerous goods transport regulations.

1,2,3,4-tetranitro-9H-carbazole is subject to strict regulations under EU CLP regulation due to its explosive and acute toxicity classifications. REACH registration requirements apply for commercial use above tonnage thresholds. Additional restrictions may apply under national explosives regulations and precursor chemical legislation. Users must comply with workplace safety directives and may need special permits or licenses for possession and use of explosive substances.
