Calcium;dinitrate;tetrahydrate

Calcium dinitrate tetrahydrate is an inorganic salt with the molecular formula CaH8N2O10 and CAS number 13477-34-4. This compound consists of calcium cations combined with nitrate anions and four molecules of water of crystallization. With a molecular weight of 236.15 g/mol, it appears as a white crystalline solid that is highly soluble in water. It is commonly used in various industrial applications due to its oxidizing properties and calcium content.

Calcium dinitrate tetrahydrate is a white crystalline solid that is highly soluble in water and hygroscopic in nature. The compound has a molecular weight of 236.15 g/mol and contains four molecules of water of crystallization. It is odorless and has a slightly bitter taste. The substance readily absorbs moisture from air and can form concentrated solutions. It decomposes at elevated temperatures, releasing nitrogen oxides and oxygen, which contributes to its oxidizing characteristics.

Calcium dinitrate tetrahydrate is primarily used as a fertilizer in agriculture, providing both calcium and nitrogen nutrients to plants. It serves as a concrete additive to accelerate setting and prevent freezing in cold weather construction. The compound is also utilized in wastewater treatment processes for odor control and as a source of calcium in various chemical manufacturing processes. Additionally, it finds applications in the production of explosives and pyrotechnics due to its oxidizing properties.

Calcium dinitrate tetrahydrate should be handled with standard laboratory safety precautions including wearing protective gloves, safety glasses, and dust masks to prevent inhalation. Work in well-ventilated areas to avoid dust accumulation. Although it has no specific GHS hazard classification, avoid creating dust clouds and prevent contact with combustible materials due to its oxidizing nature. Wash hands thoroughly after handling and ensure proper ventilation when dissolving large quantities in water as heat may be generated.

Calcium dinitrate tetrahydrate should be stored in a cool, dry place away from heat sources and direct sunlight in tightly sealed containers to prevent moisture absorption. Keep separated from combustible materials, organic substances, and reducing agents due to its oxidizing properties. Store in areas with good ventilation and maintain temperatures below 30°C. Use moisture-proof packaging and ensure containers are properly labeled. Avoid storage near acids or alkalis to prevent unwanted chemical reactions.

In case of skin contact with calcium dinitrate tetrahydrate, immediately wash the affected area with plenty of water and soap for at least 15 minutes. If eye contact occurs, rinse eyes thoroughly with clean water for at least 15 minutes and seek medical attention if irritation persists. If inhaled, move the person to fresh air immediately. In case of ingestion, rinse mouth with water and seek medical advice. Remove contaminated clothing and wash before reuse.

Calcium dinitrate tetrahydrate should be disposed of according to local and national waste regulations as it is classified as an oxidizing substance. Contact licensed waste disposal companies for proper handling and treatment. Small quantities can often be neutralized and diluted before disposal, but this should only be done following proper procedures. Never dispose of in regular household waste or pour down drains without proper treatment. Consult local environmental authorities for specific disposal requirements in your region.

Calcium dinitrate tetrahydrate is classified under ADR as Class 5.1 (Oxidizing substances), Packing Group III for transport purposes. It must be packaged in UN-approved containers with appropriate labeling indicating its oxidizing nature. During transport, keep packages dry and secure, separated from combustible materials and reducing agents. Vehicles should be well-ventilated and drivers must carry appropriate transport documentation. Follow all applicable dangerous goods transport regulations for road, rail, or sea transport.

Calcium dinitrate tetrahydrate is subject to standard chemical regulations including REACH registration in the European Union, though it is not classified as a Substance of Very High Concern (SVHC). It must comply with CLP regulation for classification, labeling, and packaging. As an oxidizing substance, it is regulated under dangerous goods transport legislation (ADR/IMDG/IATA). Users must maintain safety data sheets and follow workplace exposure guidelines. No specific restrictions apply beyond standard chemical safety regulations.
