Manufacturer Contact: Direct communications to suppliers or producer for safety information and supply chain traceability
GHS Classification: Eye irritation (Category 2), Skin irritation (Category 2), Specific target organ toxicity-single exposure (Category 3, respiratory tract irritation)
Signal Word: Warning
Hazard Statements: Causes skin irritation, causes serious eye irritation, may cause respiratory irritation
Pictograms: Exclamation mark symbol for general irritant properties
Potential Health Effects: Eyes may water or become inflamed upon contact, skin may redden, inhaled dust or powder can lead to coughing and sneezing, ingestion may cause nausea
Main Ingredient: Idebenone 99%–100%
Impurities: Trace related quinone derivatives, none exceeding safe limits for laboratory use
Form: Solid, powder or crystalline, yellow to orange in color
General Advice: Remove from exposure immediately, seek medical evaluation for significant reactions
Eye Contact: Rinse thoroughly with water for 15 minutes, remove contact lenses if present, consult physician
Skin Contact: Wash area with soap and plenty of water, remove contaminated clothing and wash before reuse
Inhalation: Relocate person to fresh air, keep comfortable for breathing, access medical care if symptoms persist
Ingestion: Rinse mouth, drink several cups of water, avoid forced vomiting, consult healthcare professional quickly
Suitable Extinguishing Media: Water spray, dry chemical powder, carbon dioxide, foam
Hazardous Combustion Products: Carbon oxides (CO, CO2), acrid fumes, benzoquinone derivatives
Fire Fighting Instructions: Wear full protective gear, self-contained breathing apparatus, avoid exposure to combustion gases, cool containers with water, stay upwind and keep exits accessible
Personal Precautions: Use personal protective equipment (PPE), ventilate area, avoid dust creation, remove ignition sources
Cleanup Methods: Sweep up material without generating dust, transfer to container for disposal, wipe area with damp cloth, decontaminate equipment
Environmental Precautions: Prevent release to sewers, soil, or waterways, report larger spills to appropriate authorities for coordinated cleanup
Handling: Operate in well-ventilated areas, avoid direct contact and inhalation, wear gloves, lab coat, and eye protection
Storage Conditions: Store in cool, dry, tightly closed containers, avoid heat, sunlight, and sources of ignition, segregate from incompatible materials, label and date all containers for inventory traceability
Special Considerations: Control moisture and limit exposure to air to preserve chemical stability
Occupational Exposure Limits: No specific limits established, handle as potentially hazardous material
Engineering Controls: Fume hoods, eyewash stations, local exhaust ventilation
Personal Protective Equipment: Safety glasses with side shields, chemical-resistant gloves, lab coats, approved respirators in cases of dust production
Hygiene Measures: Wash hands thoroughly after handling, avoid eating or drinking in the laboratory, remove contaminated clothing after use
