Cadmium(2+);dinitrate;tetrahydrate

Cadmium dinitrate tetrahydrate is an inorganic salt compound with the chemical formula CdH8N2O10 and molecular weight of 308.49 g/mol. This crystalline substance consists of cadmium ions combined with nitrate anions and four water molecules of crystallization. It is classified under CAS number 10022-68-1 and is commonly used in various industrial applications requiring cadmium compounds. The tetrahydrate form indicates the presence of four water molecules per formula unit, which affects its physical properties and stability.

Cadmium dinitrate tetrahydrate appears as white to colorless crystalline solid at room temperature. The compound is highly soluble in water due to its ionic nature and the presence of nitrate groups. It has a molecular weight of 308.49 g/mol and contains four water molecules of crystallization, which contribute to its stability under normal conditions. The substance is hygroscopic and may absorb moisture from air. It decomposes upon heating, releasing toxic cadmium compounds and nitrogen oxides.

Cadmium dinitrate tetrahydrate is primarily used in electroplating processes for applying protective cadmium coatings to metals, particularly in aerospace and marine applications. It serves as a precursor for synthesizing other cadmium compounds and catalysts in chemical manufacturing. The compound is also utilized in the production of cadmium-containing pigments and in certain specialized battery applications. Additionally, it finds use in analytical chemistry as a reagent and in research applications requiring controlled cadmium ion sources.

Cadmium dinitrate tetrahydrate requires careful handling with appropriate personal protective equipment including chemical-resistant gloves, safety goggles, and respiratory protection in poorly ventilated areas. Work should be conducted in well-ventilated areas or under fume hoods to prevent inhalation of dust or vapors. Avoid skin contact and ingestion, as cadmium compounds are toxic. Use non-sparking tools and avoid generating dust. Ensure emergency shower and eyewash stations are accessible. Train personnel on proper handling procedures and emergency response protocols.

Cadmium dinitrate tetrahydrate should be stored in tightly sealed, original containers in a cool, dry, well-ventilated area away from heat sources and direct sunlight. Keep separate from incompatible materials such as strong reducing agents, metals, and organic compounds. Store in secondary containment to prevent spills and ensure containers are properly labeled. Maintain storage temperatures below 25°C to prevent decomposition. Implement restricted access with appropriate warning signs and ensure storage areas comply with local environmental and safety regulations.

Immediate action is required for any contact with cadmium dinitrate tetrahydrate. For skin contact, remove contaminated clothing and rinse affected area with plenty of water for at least 15 minutes. If eyes are affected, flush immediately with clean water for 15-20 minutes and remove contact lenses if easily removable. In case of inhalation, move the person to fresh air immediately. If ingested, do not induce vomiting and rinse mouth with water. Seek immediate medical attention in all cases, informing medical personnel about cadmium exposure.

Cadmium dinitrate tetrahydrate must be disposed of as hazardous waste through licensed waste management companies specializing in heavy metal disposal. Never dispose of this substance in regular waste streams, sewers, or soil due to its toxic and environmentally persistent nature. Neutralization and precipitation methods may be required before final disposal. Comply with local, national, and EU regulations including the Waste Framework Directive. Maintain proper documentation and waste tracking records. Small quantities should be collected and stored safely until proper disposal arrangements can be made.

Cadmium dinitrate tetrahydrate is classified as ADR Class 6.1 (toxic substances), Packing Group III for transportation purposes. It must be packaged in UN-approved containers with appropriate labeling and documentation including safety data sheets. Transport vehicles must display proper placarding and drivers require ADR certification for toxic materials. Ensure packages are secured to prevent damage during transit and carry emergency response information. Comply with quantity limitations and routing restrictions as specified in ADR regulations for toxic substances.

Cadmium dinitrate tetrahydrate is subject to strict European regulations under REACH and CLP frameworks, though it is not currently listed as a Substance of Very High Concern (SVHC). The compound falls under cadmium restrictions in various EU directives limiting its use in consumer products. Users must comply with occupational exposure limits and environmental discharge restrictions. Registration requirements under REACH apply for quantities above one tonne per year. Additionally, specific national regulations may impose further restrictions on storage, use, and disposal of cadmium-containing compounds.
