Strontium dinitrate

Strontium dinitrate is an inorganic chemical compound with the molecular formula N2O6Sr and CAS number 10042-76-9. This salt consists of strontium cations combined with nitrate anions, forming a white crystalline solid with a molecular weight of 211.63 g/mol. It belongs to the family of alkaline earth metal nitrates and exhibits oxidizing properties due to its nitrate groups, making it useful in various industrial applications requiring controlled oxidation reactions.

Strontium dinitrate appears as a white crystalline powder or crystals that are highly soluble in water and slightly soluble in alcohol. The compound is odorless and hygroscopic, meaning it readily absorbs moisture from the atmosphere. It has a density of approximately 2.99 g/cm³ and decomposes at high temperatures rather than melting. The substance exhibits strong oxidizing properties and can support combustion when in contact with organic materials or reducing agents.

Strontium dinitrate is primarily used in pyrotechnics and fireworks manufacturing to produce brilliant red flames and colors due to strontium's characteristic emission spectrum. It serves as an oxidizer in explosive compositions and signal flares. The compound is also utilized in the production of other strontium compounds, as a corrosion inhibitor in certain applications, and in specialized glass manufacturing. Additionally, it finds use in research laboratories and analytical chemistry applications.

Strontium dinitrate should be handled with appropriate personal protective equipment including safety goggles, gloves, and protective clothing to prevent skin and eye contact. Work in well-ventilated areas to avoid dust inhalation and use dust masks when necessary. Keep the substance away from heat sources, sparks, and incompatible materials like organic compounds and reducing agents. Use non-sparking tools and avoid creating dust clouds during handling to prevent potential oxidation reactions.

Strontium dinitrate must be stored in a cool, dry, well-ventilated area away from heat sources and direct sunlight. Keep containers tightly sealed to prevent moisture absorption and contamination. Store separately from combustible materials, organic compounds, reducing agents, and acids to prevent dangerous reactions. Use appropriate containers that are compatible with oxidizing substances and ensure storage areas comply with local regulations for oxidizing materials (Class 5.1).

Strontium dinitrate contact requires immediate action: for skin contact, remove contaminated clothing and wash affected area thoroughly with soap and water for at least 15 minutes. In case of eye contact, flush immediately with clean water for 15-20 minutes and remove contact lenses if present. If inhaled, move to fresh air immediately. For ingestion, rinse mouth with water but do not induce vomiting. Seek medical attention if irritation persists or symptoms develop.

Strontium dinitrate disposal must comply with local and national hazardous waste regulations as it is classified as an oxidizing substance. Contact licensed hazardous waste disposal companies for proper treatment and disposal. Do not discharge into drains, waterways, or soil. Small quantities may be neutralized by qualified personnel following appropriate safety protocols. Always consult local environmental authorities for specific disposal requirements and approved disposal facilities in your region.

Strontium dinitrate is classified under ADR Class 5.1 (Oxidizing Substances) Packing Group III for transportation purposes. It requires appropriate hazardous materials packaging, labeling, and documentation according to dangerous goods regulations. Vehicles must carry proper placarding and emergency response information. Transport should be conducted by certified carriers experienced in handling oxidizing materials, ensuring compliance with international transport regulations for dangerous goods including IATA, IMDG, and ADR requirements.

Strontium dinitrate falls under various chemical safety regulations including REACH (Registration, Evaluation, Authorization of Chemicals) in Europe, requiring appropriate safety data sheets and risk assessments. It is not classified as a SVHC (Substance of Very High Concern) but must comply with CLP (Classification, Labelling and Packaging) regulations. Users must follow occupational safety standards and may need permits for certain quantities or applications, particularly in pyrotechnic manufacturing.
