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 aromatic ring system, giving it explosive properties. With a molecular weight of 347.2 g/mol, it belongs to the class of polynitroaromatic compounds and is classified as a Category 1.1 explosive under GHS regulations.

1,2,3,4-tetranitro-9H-carbazole typically appears as a crystalline solid with high density due to its multiple nitro groups. The compound exhibits limited solubility in most common solvents due to its highly nitrated structure and strong intermolecular interactions. Its physicochemical properties are dominated by the presence of four electron-withdrawing nitro groups, which significantly affect its stability, sensitivity, and reactivity compared to unsubstituted carbazole.

1,2,3,4-tetranitro-9H-carbazole is primarily used in specialized research applications and explosive formulations due to its energetic properties. Its applications are typically limited to controlled environments such as defense research, pyrotechnic development, and academic studies on energetic materials. The compound may also serve as an intermediate in the synthesis of other specialized nitroaromatic compounds for research purposes.

1,2,3,4-tetranitro-9H-carbazole must be handled with extreme caution due to its explosive nature and acute toxicity. Essential safety measures include wearing appropriate personal protective equipment (gloves, safety glasses, lab coat), working in well-ventilated areas or fume hoods, and avoiding friction, impact, or heat sources. Only trained personnel should handle this material, using anti-static equipment and grounding procedures to prevent accidental detonation.

1,2,3,4-tetranitro-9H-carbazole must be stored in approved explosive storage facilities with appropriate temperature and humidity control. The storage area should be isolated from incompatible materials, heat sources, and ignition sources. Containers should be properly labeled and stored in quantities compliant with local explosive storage regulations. Regular inspection of storage conditions and container integrity is essential to maintain safety and prevent degradation.

Immediate action is required in case of contact with 1,2,3,4-tetranitro-9H-carbazole due to its acute toxicity classification. For skin contact, remove contaminated clothing and rinse thoroughly with water for at least 15 minutes. In case of eye contact, flush immediately with water and seek medical attention. If inhaled, move to fresh air immediately. For ingestion, do not induce vomiting and seek immediate medical care while providing safety data sheet information to medical personnel.

1,2,3,4-tetranitro-9H-carbazole disposal must be conducted by licensed hazardous waste specialists experienced with explosive materials. The compound cannot be disposed of through normal chemical waste streams due to its explosive classification. Disposal typically involves controlled detonation or specialized treatment at authorized facilities. All disposal activities must comply with local, national, and international regulations governing explosive waste management and require proper documentation.

Transportation of 1,2,3,4-tetranitro-9H-carbazole requires compliance with dangerous goods regulations due to its explosive classification. Special packaging, labeling with GHS01 and GHS07 pictograms, and documentation are mandatory. Transport must be conducted by certified carriers experienced with explosive materials, using appropriate vehicles and routes. Specific ADR/DOT classifications and shipping requirements must be verified with transport authorities before shipment.
