1,1,1,3,3-pentafluorobutane

1,1,1,3,3-pentafluorobutane is a fluorinated organic compound with the molecular formula C4H5F5 and CAS number 406-58-6. This synthetic chemical features five fluorine atoms attached to a four-carbon chain, giving it unique properties typical of fluorinated compounds. With a molecular weight of 148.07 g/mol, it belongs to the family of hydrofluorocarbons (HFCs) and is classified as a flammable liquid requiring careful handling and storage procedures.

1,1,1,3,3-pentafluorobutane is a colorless liquid at room temperature with low viscosity typical of fluorinated compounds. The presence of multiple fluorine atoms gives it low surface tension and reduced intermolecular forces compared to non-fluorinated analogs. It exhibits limited solubility in water due to its hydrophobic fluorinated structure but shows good compatibility with organic solvents. The compound has a relatively low boiling point and high vapor pressure.

1,1,1,3,3-pentafluorobutane serves as a specialty solvent in various industrial applications, particularly in electronics cleaning and precision degreasing operations. It functions as an intermediate in the synthesis of other fluorinated compounds and specialty chemicals. The compound is also utilized in aerosol formulations and as a component in specialized cleaning systems where its unique solvency properties and low surface tension are advantageous for removing contaminants from sensitive surfaces.

1,1,1,3,3-pentafluorobutane must be handled with appropriate safety precautions due to its Flam. Liq. 2 classification. Work in well-ventilated areas or under fume extraction to prevent vapor accumulation. Wear appropriate personal protective equipment including safety glasses, chemical-resistant gloves, and flame-resistant clothing. Eliminate all ignition sources including static electricity, sparks, and open flames. Use non-sparking tools and ensure proper grounding of equipment to prevent static discharge during handling operations.

1,1,1,3,3-pentafluorobutane requires storage in a cool, dry, well-ventilated area away from heat sources, ignition sources, and direct sunlight. Store in tightly sealed, compatible containers to prevent vapor loss and contamination. Keep away from oxidizing agents and incompatible materials. Maintain storage temperature below flash point and ensure adequate fire protection systems are in place. Use appropriate secondary containment and ensure storage areas comply with local fire safety regulations for flammable liquids.

Immediate action is required upon contact with 1,1,1,3,3-pentafluorobutane to minimize potential health effects. For skin contact, remove contaminated clothing and wash affected area thoroughly with soap and water. In case of eye contact, flush immediately with clean water for at least 15 minutes and seek medical attention. If inhaled, move person to fresh air and monitor breathing. For ingestion, do not induce vomiting and seek immediate medical attention. Always consult safety data sheet for specific first aid measures.

1,1,1,3,3-pentafluorobutane disposal must comply with local, national, and international waste regulations as it is classified as hazardous waste. Contact licensed waste disposal companies specialized in handling fluorinated organic compounds. Do not discharge into drains, waterways, or soil. Consider recovery and recycling options where available. Incineration should only be performed at authorized high-temperature facilities equipped with appropriate emission control systems to prevent release of hydrogen fluoride and other toxic combustion products.

1,1,1,3,3-pentafluorobutane is classified under ADR Class 3, Group II, requiring specific transport procedures for flammable liquids. Use approved packaging and containers designed for Group II flammable liquids. Vehicles must display appropriate hazard placards and carry emergency response information. Drivers require ADR training certification. Ensure proper loading, securing, and documentation procedures are followed. Transport during cooler periods when possible and avoid routes through densely populated areas or environmentally sensitive zones.

1,1,1,3,3-pentafluorobutane is subject to multiple regulatory frameworks including REACH registration requirements in the European Union. It falls under CLP regulation for classification and labeling as Flam. Liq. 2 with GHS02 pictogram. The compound is not currently listed as a Substance of Very High Concern (SVHC). Users must comply with national chemical safety regulations, workplace exposure limits, and environmental protection requirements. Regular review of regulatory status is recommended as fluorinated compounds face increasing scrutiny.
