The compound has a molecular weight of 484.06 g/mol and maintains its crystalline structure when properly stored away from heat and moisture.

Tetrasodium iron(2+) hexacyanide decahydrate is primarily used as an anti-caking agent in food processing, particularly in salt production. It serves as a laboratory reagent for analytical chemistry applications and is employed in the manufacturing of pigments, specifically Prussian blue. The compound also finds use in metal surface treatment processes and as a source of ferrocyanide ions in various industrial chemical syntheses and water treatment applications.

Tetrasodium iron(2+) hexacyanide decahydrate should be handled with standard laboratory safety precautions including wearing safety glasses, gloves, and protective clothing. Work in well-ventilated areas and avoid creating dust. Although this compound has no specific GHS pictograms or signal words, good chemical hygiene practices should be followed. Avoid contact with strong acids which could release toxic hydrogen cyanide gas. Wash hands thoroughly after handling and avoid eating, drinking, or smoking in work areas.

Tetrasodium iron(2+) hexacyanide decahydrate should be stored in a cool, dry place in tightly sealed containers to prevent moisture absorption and decomposition. Keep away from heat sources, direct sunlight, and strong acids. Store in original packaging or compatible containers made of suitable materials. Maintain storage temperatures below 25°C and ensure good ventilation in storage areas. Keep separate from incompatible materials such as strong oxidizing agents and acids to prevent unwanted reactions.

In case of skin contact with tetrasodium iron(2+) hexacyanide decahydrate, immediately wash the affected area with plenty of soap and water for at least 15 minutes. For eye contact, flush eyes with clean water for 15 minutes while holding eyelids open. If inhaled, move the person to fresh air immediately. In case of ingestion, rinse mouth with water and seek medical attention. Although the compound has no specific hazard classification, always consult a physician if symptoms persist or if large amounts were involved.

Tetrasodium iron(2+) hexacyanide decahydrate waste should be disposed of according to local and national environmental regulations. Contact licensed waste disposal companies for proper treatment and disposal. Do not discharge into sewers, waterways, or soil without proper treatment. Small laboratory quantities may be neutralized and treated according to institutional waste management protocols. Always check with local environmental authorities for specific disposal requirements and approved waste treatment facilities in your region.

Tetrasodium iron(2+) hexacyanide decahydrate is classified under ADR transport regulations as Class 6.1 (toxic substances), requiring appropriate packaging and labeling for shipment. Use UN-approved packaging suitable for Class 6.1 materials and ensure proper documentation including safety data sheets. Vehicles must carry appropriate placards and emergency equipment. Drivers require ADR certification for transporting dangerous goods. Always comply with national and international transport regulations and consult current ADR guidelines for specific packaging and documentation requirements.

Tetrasodium iron(2+) hexacyanide decahydrate is subject to REACH regulation in Europe, requiring registration for import or manufacture above certain tonnages.
