Phenylmercury;hydrate

Phenylmercury hydrate is an organomercury compound with the molecular formula C6H7HgO and CAS number 100-57-2. This chemical substance has a molecular weight of 295.71 g/mol and belongs to the class of phenylmercury derivatives. It contains mercury bonded to a phenyl group with associated water molecules in its crystal structure, making it a hydrated form of phenylmercury compounds used in various industrial applications.

Phenylmercury hydrate is a solid organomercury compound at room temperature with the molecular formula C6H7HgO. As a mercury-containing organic compound, it typically appears as a crystalline solid. The presence of the hydrate form indicates water molecules are incorporated into its crystal structure. Being an organomercury compound, it exhibits limited water solubility but may dissolve in organic solvents.

Phenylmercury hydrate is primarily used as a fungicide and antimicrobial agent in industrial applications. Historically, it has been employed in agricultural formulations, wood preservation treatments, and as a biocide in various industrial processes. Due to its mercury content, its use has become increasingly restricted in many applications, with modern alternatives being preferred for environmental and safety reasons.

Phenylmercury hydrate requires careful handling due to its mercury content and potential toxicity. Always wear appropriate personal protective equipment including nitrile gloves, safety goggles, and respiratory protection when handling. Work in well-ventilated areas or under fume hoods to prevent inhalation exposure. Avoid skin contact and ingestion. Use proper laboratory techniques and ensure all personnel are trained in mercury compound handling procedures.

Phenylmercury hydrate should be stored in tightly sealed containers in a cool, dry, and well-ventilated area away from incompatible materials. Keep containers away from heat sources, direct sunlight, and moisture. Store separately from food, beverages, and animal feed. Ensure storage areas have appropriate spill containment measures and are accessible only to authorized personnel trained in handling mercury-containing compounds.

In case of skin contact with phenylmercury hydrate, immediately remove contaminated clothing and wash the affected area thoroughly with soap and water for at least 15 minutes. If eye contact occurs, flush eyes with clean water for 15 minutes while holding eyelids open. In case of inhalation, move to fresh air immediately. For ingestion, do not induce vomiting and seek immediate medical attention, informing healthcare providers about mercury exposure.

Phenylmercury hydrate must be disposed of as hazardous waste containing mercury through licensed waste management facilities. Never dispose of this substance in regular waste streams, sewers, or the environment. Contact specialized hazardous waste disposal companies that can handle mercury-containing compounds. Follow all local, national, and EU regulations regarding mercury waste disposal, including proper documentation and tracking requirements for hazardous waste transfers.

Phenylmercury hydrate is classified under ADR as Class 6.1 (toxic substances) with Packing Group II, indicating moderate toxicity requiring specific transport precautions. It must be packaged in UN-approved containers with appropriate labeling and documentation. Transport vehicles must carry proper emergency equipment and drivers need hazardous materials training. Comply with all ADR regulations for toxic substances during shipping and handling.

Phenylmercury hydrate is subject to strict regulations due to its mercury content under various European and international frameworks. It falls under REACH registration requirements and mercury-specific restrictions. Many jurisdictions have banned or severely limited its use in consumer products and certain industrial applications. Users must comply with occupational exposure limits, environmental discharge restrictions, and waste management regulations specific to mercury-containing substances.

Phenylmercury hydrate is available through OYSI, a specialized European distributor of technical chemicals. As a professional chemical supplier, OYSI can provide this substance to qualified industrial customers with appropriate handling capabilities and regulatory compliance. Due to the restricted nature of mercury compounds, purchases typically require verification of legitimate industrial use and proper safety measures for handling and storage.
