Chloromercury

Chloromercury is an inorganic mercury compound with the chemical formula Cl2Hg2 and CAS number 10112-91-1. This substance has a molecular weight of 472.09 g/mol and belongs to the family of mercury halides. It is classified as a hazardous chemical with multiple danger classes including acute toxicity, specific target organ toxicity, skin and eye irritation, and environmental hazards. The compound requires careful handling due to its toxic properties and environmental impact.

Chloromercury is a solid inorganic compound at room temperature with the molecular formula Cl2Hg2. The substance has a molar mass of 472.09 g/mol and contains mercury in its chemical structure. As a mercury-containing compound, it typically appears as a crystalline solid. Its physical properties require careful consideration during handling due to the presence of mercury, which contributes to its hazardous classification and environmental concerns.

Chloromercury serves as a specialized chemical reagent primarily in research and analytical applications. The compound is typically used in laboratory settings for specific chemical synthesis processes and analytical procedures where mercury-containing compounds are required. Due to its hazardous nature and environmental impact, its use is generally restricted to professional and industrial applications with appropriate safety measures and regulatory compliance in place.

Chloromercury requires strict safety precautions including appropriate personal protective equipment such as chemical-resistant gloves, safety goggles, and protective clothing. Work should be conducted in well-ventilated areas or under fume hoods to prevent inhalation exposure. Given its Acute Tox. 4 classification and skin/eye irritant properties, direct contact must be avoided. Personnel should be trained in mercury compound handling procedures and emergency response protocols before working with this substance.

Chloromercury must be stored in a secure, well-ventilated area away from incompatible materials and heat sources. The substance should be kept in its original, tightly sealed containers to prevent contamination and exposure. Storage areas should be restricted to authorized personnel only, with appropriate labeling displaying GHS07 and GHS09 pictogrammes and warning signals. Temperature and humidity control may be necessary to maintain product stability and prevent degradation.

Chloromercury exposure requires immediate first aid measures depending on the contact route. For skin contact, remove contaminated clothing and rinse affected areas thoroughly with water for at least 15 minutes. In case of eye contact, flush immediately with clean water and seek medical attention. If inhaled, move the person to fresh air immediately. Due to its toxic properties, medical evaluation should be sought promptly after any exposure incident, regardless of severity.

Chloromercury disposal requires specialized hazardous waste management procedures due to its mercury content and environmental toxicity classification (Aquatic Acute 1, Aquatic Chronic 1). The substance must be collected and disposed of through licensed hazardous waste contractors following local and European regulations. It cannot be disposed of in regular waste streams or sewage systems. Proper documentation and waste tracking procedures must be maintained throughout the disposal process.

Chloromercury is classified under ADR Class 6.1 (Toxic substances), Packing Group III for transportation purposes. The substance requires appropriate packaging, labeling, and documentation according to dangerous goods regulations. Transport vehicles must comply with ADR requirements for toxic substances, and drivers need proper training and certification. Shipping documentation must include proper shipping names, hazard classes, and emergency response information for safe transport across European borders.

Chloromercury is subject to extensive European chemical regulations including REACH registration requirements and CLP classification and labeling obligations. The substance is not currently listed as an SVHC (Substance of Very High Concern), but its mercury content may subject it to additional restrictions under various environmental and occupational health regulations. Companies handling this substance must ensure compliance with national mercury regulations and maintain appropriate safety data sheets and exposure assessments.

Chloromercury is available through specialized chemical distributors such as OYSI, a European distributor of technical chemicals. Due to its hazardous classification and regulatory requirements, procurement typically requires proper documentation, safety qualifications, and compliance verification. Professional customers should contact OYSI directly for availability, technical specifications, and regulatory support. Purchase may be restricted to qualified industrial and research users with appropriate handling capabilities and permits.
