1,1-dichloro-1-nitroethane

1,1-dichloro-1-nitroethane is an organochlorine compound with the molecular formula C2H3Cl2NO2 and CAS number 594-72-9. This chemical substance has a molecular weight of 143.95 g/mol and belongs to the class of nitroalkanes containing two chlorine atoms. It is classified as a highly toxic substance under GHS regulations, requiring careful handling and appropriate safety measures in industrial and laboratory applications.

1,1-dichloro-1-nitroethane is typically a colorless to pale yellow liquid at room temperature with a characteristic chemical odor. The compound has a density higher than water due to its chlorine content and exhibits limited water solubility. Its physicochemical properties include stability under normal conditions, though it may decompose under extreme heat or in the presence of strong bases, making proper storage conditions essential.

1,1-dichloro-1-nitroethane is primarily used as a chemical intermediate in organic synthesis and pharmaceutical manufacturing. It serves as a building block for the production of various nitrogen-containing compounds and can be utilized in specialized chemical reactions. The compound may also find applications in research and development activities within the chemical industry, particularly in the synthesis of more complex molecular structures.

1,1-dichloro-1-nitroethane requires strict safety protocols due to its Acute Tox. 3 classification and GHS06 pictogram indicating acute toxicity. Essential personal protective equipment includes chemical-resistant gloves, safety goggles, and appropriate respiratory protection. Work should be conducted in well-ventilated areas or under fume hoods. Avoid skin contact, inhalation, and ingestion. Emergency eyewash stations and safety showers should be readily accessible during handling operations.

1,1-dichloro-1-nitroethane should be stored in tightly sealed containers in a cool, dry, well-ventilated area away from heat sources and direct sunlight. The storage area must be separated from incompatible materials such as strong oxidizing agents, bases, and reactive metals. Containers should be properly labeled with hazard information and stored in secondary containment systems to prevent environmental contamination in case of leakage.

Immediate first aid measures for 1,1-dichloro-1-nitroethane exposure include removing contaminated clothing and flushing affected skin with plenty of water for at least 15 minutes. In case of eye contact, rinse thoroughly with water and seek immediate medical attention. If inhaled, move the person to fresh air and provide oxygen if breathing difficulties occur. Never induce vomiting if ingested. Seek immediate medical attention for all exposure routes due to the substance's high toxicity.

1,1-dichloro-1-nitroethane disposal must comply with local, national, and European waste regulations as a hazardous chemical waste. The substance cannot be disposed of through regular waste streams and requires specialized treatment at licensed hazardous waste facilities. Incineration at high temperatures in approved facilities is typically the preferred disposal method. Always consult with certified waste management companies and follow all applicable environmental regulations for proper disposal.

1,1-dichloro-1-nitroethane is classified under ADR Class 6.1 (toxic substances) Packing Group II, indicating moderate toxicity during transport. The substance requires appropriate UN-specification packaging, proper labeling with toxic hazard symbols, and accompanying transport documents. Only certified carriers experienced in handling toxic chemicals should transport this material. Emergency response information must be available during transport, and drivers must hold appropriate dangerous goods certifications.

1,1-dichloro-1-nitroethane is subject to European REACH regulation requiring registration for commercial use and falls under CLP classification for hazard communication. While not currently listed as an SVHC (Substance of Very High Concern), it must comply with workplace exposure limits and industrial emissions regulations. Users must maintain safety data sheets, implement risk management measures, and may need to report usage depending on quantities and applications under various chemical safety regulations.
