Overview

Fluorane (CAS 7664-39-3) is a binary hydrogen halide compound with highly corrosive properties and extreme toxicity. Fluorane, also known by its IUPAC designation, represents one of the most hazardous hydrogen halides in industrial chemistry. With the molecular formula FH and a molecular weight of 20.0064 g/mol, this compound exhibits exceptionally dangerous characteristics that demand rigorous safety protocols in all handling procedures. The substance carries multiple acute toxicity classifications and is classified as a skin corrosive category 1A material, requiring specialized expertise for safe industrial use. The compound's severe hazard profile is reflected in its GHS classification system, displaying both the skull and crossbones pictogram (GHS06) for acute toxicity and the corrosion pictogram (GHS05) for its destructive effects on skin and materials. As an ADR class 8 substance, fluorane requires specialized transport protocols due to its corrosive nature. The "Danger" signal word emphasizes the critical importance of proper safety measures when working with this material. In industrial applications, fluorane serves primarily in specialized chemical synthesis processes, semiconductor manufacturing operations, and as a reagent in advanced materials production. Its unique reactivity profile makes it valuable for specific etching processes and in the preparation of fluorinated compounds. Like other highly reactive halogen compounds such as pentachloro-lambda5-phosphane and tribromoborane, fluorane requires controlled atmospheric conditions and specialized containment systems. Due to its extreme hazard classification, fluorane handling necessitates comprehensive safety training, appropriate personal protective equipment, and engineered containment systems. Industrial users must implement strict protocols for storage, handling, and waste management to ensure worker safety and regulatory compliance. OYSI maintains specialized capabilities for sourcing and distributing high-hazard chemical compounds like fluorane to qualified industrial customers across Europe.

Frequently Asked Questions

What is fluorane?

Fluorane is hydrogen fluoride (HF), a highly corrosive and toxic inorganic compound with the molecular formula FH and CAS number 7664-39-3. It has a molecular weight of 20.0064 g/mol and is classified as an extremely hazardous chemical with acute toxicity and severe corrosive properties. Fluorane is one of the most dangerous acids, capable of dissolving glass and causing severe chemical burns upon contact with skin or inhalation.

What are the physicochemical properties of fluorane?

Fluorane exists as a colorless gas at room temperature with a sharp, penetrating odor. It is highly soluble in water, forming hydrofluoric acid solutions. The compound has exceptional chemical reactivity, particularly with silica-containing materials like glass. It demonstrates strong hydrogen bonding capabilities and can penetrate deeply into tissues. Fluorane vapors are heavier than air and can accumulate in low-lying areas, presenting additional safety concerns during handling.

What is fluorane used for?

Fluorane is primarily used in industrial applications including glass etching, semiconductor manufacturing, and metal surface treatment. It serves as a key reagent in fluorine chemistry for producing organofluorine compounds and fluorinated materials. The chemical industry utilizes fluorane for petroleum refining processes, particularly in alkylation reactions. It is also employed in the production of fluorinated polymers and as a catalyst in various chemical synthesis processes requiring strong acidic conditions.

How to handle fluorane safely?

Fluorane handling requires extreme caution with comprehensive personal protective equipment including acid-resistant gloves, full face shields, and respiratory protection. Work must be conducted in well-ventilated areas or fume hoods with emergency shower facilities nearby. Personnel should wear chemical-resistant clothing and ensure calcium gluconate gel is immediately available for emergency treatment. All handling procedures must follow strict protocols with trained personnel only, and emergency response plans should be established before use.

How to store fluorane correctly?

Fluorane must be stored in specially designed, corrosion-resistant containers made from materials like polyethylene or Teflon, never in glass or metal containers. Storage areas should be cool, dry, and well-ventilated with appropriate containment systems. The substance must be kept away from incompatible materials including metals, glass, concrete, and organic materials. Secondary containment and specialized storage cabinets designed for corrosive materials are essential for safe storage.

What to do in case of contact with fluorane?

Immediate action is critical for fluorane exposure - flush affected skin or eyes with copious amounts of water for at least 15 minutes while removing contaminated clothing. Apply calcium gluconate gel to affected skin areas and seek immediate medical attention. For inhalation, move the victim to fresh air immediately and provide oxygen if breathing is difficult. Do not induce vomiting if ingested. Emergency medical treatment is essential in all cases due to fluorane's severe toxicity and delayed effects.

How to dispose of fluorane appropriately?

Fluorane disposal must comply with strict hazardous waste regulations and requires specialized treatment facilities licensed for corrosive and toxic materials. The substance cannot be disposed of through normal waste streams and must be neutralized by qualified professionals using appropriate neutralizing agents. Collection, transportation, and treatment must follow ADR dangerous goods regulations. Waste containers must be properly labeled and handled by certified hazardous waste disposal companies with appropriate permits and expertise.

How to transport fluorane?

Fluorane transportation is regulated under ADR Class 8 (corrosive substances) with Packing Group I classification, indicating maximum danger level. Specialized packaging, labeling with GHS06 and GHS05 pictograms, and proper documentation are mandatory. Transport vehicles must carry appropriate emergency equipment and drivers require ADR certification. Shipments must comply with dangerous goods regulations including quantity restrictions, route planning, and emergency response procedures. Only authorized carriers with proper certifications can transport this substance.
