Name: Methoxyethylmercury Chloride
Chemical Formula: C5H11ClHgO
Appearance: Generally presents as a pale solid or crystalline material, faint odor, low volatility
Common Uses: Research chemical, occasionally turned up in specialty synthesis in academic labs
CAS Number: 10067-41-3
Acute Toxicity: Highly toxic if swallowed, inhaled, or absorbed through the skin
Health Hazards: Central nervous system impairment, kidney damage, severe eye and skin irritation, possible reproductive effects, high cumulative toxicity
Environmental Hazards: Causes long-lasting effects to aquatic organisms
Risk Symbols: Skull and crossbones, environmental hazard pictogram
Routes of Exposure: Inhalation, skin contact, ingestion
Main Ingredient: Methoxyethylmercury Chloride – almost pure in research settings
Impurities: Depending on synthesis, may contain trace levels of related mercury compounds
Concentration: Generally exceeds 98% for lab-grade samples
If Inhaled: Get to fresh air, support breathing—professional medical help required
If Swallowed: Do not induce vomiting, rinse the mouth if safe, seek urgent care with information on compound
If on Skin: Remove contaminated clothing, wash skin with soap and water thoroughly, get checked as soon as possible
If in Eyes: Rinse eyes with water for 15 minutes, hold eyelids apart, emergency treatment needed
Note to Physician: Symptoms may have delayed onset; watch for neurological and renal decline
Flammability: Product itself is generally not highly flammable but can give off hazardous fumes under heat
Suitable Extinguishing Media: Dry chemical, CO2, alcohol-resistant foam, sand
Special Equipment: Full protective gear and self-contained breathing apparatus
Hazards: Decomposition may release corrosive and toxic vapors of mercury, hydrogen chloride, and organics
Personal Protection: Put on a respirator, chemical gloves, protective clothing
Containment: Avoid dispersal, stop leak if safe, prevent entry into sewage or water systems
Cleanup: Use inert absorbent material, seal in labeled hazardous waste containers
Ventilation: Increase airflow to dilute vapor concentration, avoid confined spaces during cleanup
Handling: Always work in a fume hood, avoid skin or eye contact, never eat or drink in work area
Storage: Keep in tightly closed containers, store in cool, well-ventilated cabinets away from acids and bases
Incompatibilities: Sensitive to oxidizers, strong acids, some metals can react with contents
Labeling: Clear hazard labeling and restricted access for research or controlled use only
Occupational Exposure Limit: Mercury exposure limits hover around 0.1 mg/m³ (time-weighted average), though lower limits are safer
Personal Protection: Chemical-resistant gloves (preferably nitrile or butyl), lab coat, goggles, and always a fit-tested respirator for any airborne risk
Engineering Controls: Certified fume hood a must, containment and local exhaust to capture vapors or dust
Hygiene Measures: Wash hands meticulously after use, remove contaminated clothing before leaving work area
Physical State: Solid at room temperature
Odor: Faintly ether-like if any detectable odor
Color: Pale white or off-white
Solubility: Some solubility in organic solvents like methanol and ethanol, low in water
Melting Point: Data spotty, but may start to soften around 55–60°C
Vapor Pressure: Low at ambient temperature
Other Notable Properties: Mercury compounds can volatilize over time, so keep containment tight
Stability: Reasonably stable under standard conditions, highly sensitive to light, heat, and open air in the long run
Reactivity: Reactive with strong acids, bases, oxidizing agents
Decomposition Products: Releases highly toxic fumes—organic mercury, hydrochloric acid, possible carbon oxides
Conditions to Avoid: Heat, direct sunlight, incompatible chemicals
Absorption: Absorbed efficiently through skin, inhalation, and digestive tract
Symptoms: Headache, nausea, neurological decline, tremors, kidney pain, visual disturbance
Chronic Effects: Mercury bioaccumulates, increasing risk with each exposure—long-term exposure linked to brain and organ damage
Carcinogenic Status: Mercury compounds flagged by health agencies for possible carcinogenicity, clear evidence of neurotoxicity
Target Organs: Brain, kidneys, liver, peripheral nerves
Aquatic Toxicity: Highly toxic to aquatic life, persistent organic mercury adsorbs in sediments
Bioaccumulation: Accumulates up the food chain—fish and birds show drastic effects
Environmental Fate: Mercury compounds circulate for decades, resist natural breakdown, spread far beyond spill source
Mobility: Binds in soils and sediments, low mobility in clean water, moves rapidly in the presence of organic matter
Hazardous Waste: Treated as hazardous at every stage, no landfill or drain disposal
Method: Chemical denaturation and secure incineration in mercury-handling facilities
Secondary Containment: Transport in rigid, sealed containers to limit potential for leaks or vapor release
Transport Category: Highly regulated as a toxic and environmentally dangerous mercury compound
Packaging: Triple packaging with impact-resistant materials, extensive hazard labeling
Restrictions: Many countries sharply limit airborne and seaborne transport because of high contamination risk
Spill Protocol: Immediate reporting requirement for leaks or accidental releases
Legal Controls: Subject to international treaties and national chemical weapons conventions, mercury regulations have become more strict over the past decade
Reporting: Usage and disposal often have to be documented and reported
Worker Protection: Stringent occupational exposure requirements, health surveillance, and regular air monitoring are standard
Environmental Release: Large penalties for unauthorized releases—disposal and storage facilities demand governmental licenses and frequent inspection
