Sodium;fluoride;hydrofluoride

Sodium fluoride hydrofluoride is an inorganic chemical compound with the molecular formula F2HNa and CAS number 1333-83-1. This substance has a molecular weight of 61.9946 g/mol and is classified as a corrosive material with acute toxicity properties. It is commonly known as sodium hydrogen difluoride or sodium bifluoride and appears as a white crystalline solid that is highly soluble in water.

Sodium fluoride hydrofluoride is a white crystalline solid at room temperature with high water solubility. The compound is hygroscopic, meaning it readily absorbs moisture from air. It has a molecular weight of 61.9946 g/mol and typically appears as odorless crystals or powder. The substance is highly corrosive and releases hydrogen fluoride when in contact with acids or moisture.

Sodium fluoride hydrofluoride is primarily used in industrial applications including metal surface treatment, glass etching, and as a cleaning agent for removing rust and mineral deposits. It serves as an intermediate in fluorine chemistry and is utilized in the production of other fluoride compounds. The substance is also employed in specialized cleaning formulations and certain electroplating processes.

Sodium fluoride hydrofluoride must be handled with extreme caution due to its Acute Tox. 3 and Skin Corr. 1B classifications. Essential PPE includes chemical-resistant gloves, safety goggles, face protection, and protective clothing. Work in well-ventilated areas or under fume extraction systems. Avoid contact with skin, eyes, and respiratory tract. Always have calcium gluconate gel available for emergency treatment of potential fluoride burns.

Sodium fluoride hydrofluoride should be stored in tightly sealed, corrosion-resistant containers in a cool, dry, well-ventilated area away from incompatible materials. Keep away from acids, metals, and organic materials to prevent dangerous reactions. Store separately from food, feed, and drinking water. Ensure storage areas are equipped with appropriate spill containment and emergency response materials including calcium compounds for neutralization.

Immediate action is required in case of contact with sodium fluoride hydrofluoride. For skin contact, remove contaminated clothing and flush affected area with copious amounts of water for at least 15 minutes, then apply calcium gluconate gel. For eye contact, irrigate immediately with water for 15 minutes. If inhaled, move to fresh air. Seek immediate medical attention in all cases, emphasizing fluoride exposure to medical personnel.

Sodium fluoride hydrofluoride disposal must comply with local and national hazardous waste regulations due to its corrosive and toxic properties. The substance cannot be disposed of in regular waste streams and requires treatment by licensed hazardous waste disposal companies. Neutralization with calcium compounds may be required before disposal. Always consult local environmental authorities and follow proper waste classification procedures according to applicable legislation.

Sodium fluoride hydrofluoride is classified under ADR Class 8 (corrosive substances) with Packing Group II, indicating medium danger level. Transportation requires appropriate UN-specification packaging, proper labeling with GHS05 and GHS06 pictograms, and accompanying transport documents. Vehicles must be equipped with appropriate emergency equipment and drivers need proper training for handling corrosive materials during transport.

Sodium fluoride hydrofluoride is subject to multiple regulatory frameworks including REACH registration requirements, CLP classification as Acute Tox. 3 and Skin Corr. 1B, and ADR transport regulations. The substance is not currently listed as an SVHC under REACH. Users must comply with occupational safety regulations, environmental protection laws, and proper classification and labeling requirements under the GHS system.
