Disilver;oxalate

Disilver oxalate is an inorganic chemical compound with the molecular formula C2Ag2O4 and CAS number 533-51-7. This silver salt of oxalic acid has a molecular weight of 303.76 g/mol and appears as a white to pale yellow crystalline powder. It is classified as an acute toxicity hazard (Category 4) and requires careful handling due to its toxic properties when ingested or in contact with skin.

Disilver oxalate is a white to pale yellow crystalline solid at room temperature with no characteristic odor. The compound is poorly soluble in water but may dissolve in ammonia solutions. It is light-sensitive and may decompose upon exposure to UV radiation or elevated temperatures. The material has a high density due to its silver content and should be protected from light during storage and handling.

Disilver oxalate is primarily used in analytical chemistry as a reagent for precipitation reactions and in the synthesis of other silver compounds. It serves as a precursor in the preparation of silver nanoparticles and finds applications in specialized photographic processes. The compound is also utilized in research laboratories for organic synthesis reactions where silver salts act as oxidizing agents or catalysts.

Disilver oxalate requires careful handling using appropriate personal protective equipment including nitrile gloves, safety goggles, and lab coats. Work should be conducted in well-ventilated areas or under fume hoods to prevent inhalation. Avoid skin and eye contact, and never ingest the material. Keep away from heat sources and direct sunlight. Wash hands thoroughly after handling and ensure proper hygiene protocols are followed.

Disilver oxalate should be stored in tightly sealed containers in a cool, dry, and dark place away from direct sunlight and heat sources. The storage area must be well-ventilated and separated from incompatible materials such as strong acids, bases, and reducing agents. Keep containers properly labeled and ensure storage temperatures remain below 25°C to prevent decomposition and maintain product stability.

In case of skin contact with disilver oxalate, immediately remove contaminated clothing and wash the affected area thoroughly with soap and water for at least 15 minutes. For eye contact, rinse immediately with clean water for 15 minutes and seek medical attention. If ingested, do not induce vomiting, rinse mouth with water, and seek immediate medical help. In case of inhalation, move to fresh air and consult a physician if symptoms persist.

Disilver oxalate must be disposed of as hazardous chemical waste according to local and national regulations. Contact licensed waste disposal companies specializing in heavy metal-containing materials. Do not discharge into sewers, waterways, or regular waste streams. Small quantities should be collected in appropriate containers, properly labeled, and handed over to certified waste management facilities that can recover silver content through specialized treatment processes.

Disilver oxalate transport requirements depend on quantity and packaging specifications. While specific ADR classification details are not provided, the compound should be transported in appropriate containers with proper labeling indicating its toxic properties. Ensure packaging meets UN specification requirements for chemical transport, include safety data sheets, and comply with local transportation regulations for hazardous materials. Professional logistics companies experienced with chemical transport are recommended.

Disilver oxalate is subject to European REACH regulation and CLP classification requirements due to its acute toxicity properties (Category 4). It requires appropriate hazard labeling with GHS07 pictogram and 'Warning' signal word. The compound is not currently listed as a Substance of Very High Concern (SVHC). Users must comply with occupational safety regulations and may need to register usage depending on quantities handled and commercial applications.
