Calcium;dinitrate;tetrahydrate

Calcium dinitrate tetrahydrate is an inorganic salt with the chemical formula CaH8N2O10 and CAS number 13477-34-4. This compound consists of calcium cations combined with nitrate anions and four water molecules 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 serves as an important source of both calcium and nitrogen in various applications.

Calcium dinitrate tetrahydrate appears as white crystalline granules or powder at room temperature. The compound is highly hygroscopic and readily dissolves in water, forming clear solutions. It has excellent thermal stability under normal conditions but decomposes at elevated temperatures. The tetrahydrate form contains four molecules of water per formula unit, contributing to its crystalline structure and physical appearance.

Calcium dinitrate tetrahydrate serves primarily as a fertilizer component, providing both calcium and nitrogen nutrients for plant growth. It finds extensive use in agriculture for soil amendment and plant nutrition, particularly in hydroponic systems. The compound also functions as a concrete additive to accelerate setting times and improve cold-weather performance. Additionally, it serves as a raw material in the production of other calcium compounds and specialty chemicals.

Calcium dinitrate tetrahydrate requires standard chemical handling precautions despite having no specific hazard classification. Wear appropriate personal protective equipment including safety glasses, gloves, and protective clothing to prevent skin and eye contact. Ensure adequate ventilation in work areas and avoid generating dust clouds. Wash hands thoroughly after handling and avoid eating, drinking, or smoking in work areas. Keep the material away from incompatible substances.

Calcium dinitrate tetrahydrate should be stored in a cool, dry, well-ventilated area away from direct sunlight and heat sources. Keep containers tightly sealed to prevent moisture absorption due to its hygroscopic nature. Store separately from combustible materials, organic compounds, and reducing agents as it is classified as an oxidizing substance (ADR Class 5.1). Use appropriate containment to prevent spillage and maintain proper inventory control.

Calcium dinitrate tetrahydrate contact requires immediate response measures. For skin contact, remove contaminated clothing and wash the affected area thoroughly with soap and water. In case of eye contact, rinse immediately with plenty of clean water for at least 15 minutes and seek medical attention. If inhaled, move the person to fresh air and seek medical advice if respiratory irritation occurs. For ingestion, rinse mouth and seek immediate medical attention.

Calcium dinitrate tetrahydrate disposal must comply with local and national waste management regulations. The material should not be disposed of in regular household waste due to its oxidizing properties. Contact licensed waste disposal companies experienced in handling inorganic chemicals. Small quantities may be diluted and neutralized according to local environmental regulations. Always consult with waste management authorities before disposal to ensure compliance with applicable environmental legislation.

Calcium dinitrate tetrahydrate is classified as ADR Class 5.1 (Oxidizing substances) Packing Group III for transportation purposes. This classification requires specific packaging, labeling, and documentation according to dangerous goods regulations. Use UN-approved packaging and display appropriate hazard labels and placards. Transport vehicles must comply with ADR requirements for oxidizing substances, and drivers need appropriate dangerous goods training certificates.

Calcium dinitrate tetrahydrate falls under standard chemical regulations including REACH registration requirements for commercial use in the European Union. The substance is not classified as SVHC (Substance of Very High Concern) and has no specific GHS hazard classification. However, it remains subject to general chemical safety legislation, occupational health regulations, and transport regulations due to its oxidizing properties under ADR classification.
