Appearance
Light orange to deep orange waxy solid, odorless, with uniform color and no visible impurities. It has a waxy texture at room temperature, softens slightly when warmed, and becomes a viscous liquid at temperatures above 45°C. The pure product is bright orange, while the industrial grade may appear slightly darker. It is insoluble in water but dissolves readily in organic solvents, forming clear orange solutions.
Physical Properties
Melting point: 41-43°C (lit.), low melting point, waxy solid at room temperature, and stable when stored below 30°C. Boiling point: Predicted to be 826.8±65.0°C (760 mmHg), extremely high boiling point, and decomposes before reaching boiling point under normal pressure, releasing small molecular compounds.
Density: 0.97±0.1 g/cm3 (25°C, predicted), typical lipid-soluble density, stable in solid state under normal temperature and pressure. Solubility: Insoluble in water; soluble in ether, acetone, benzene, chloroform and other organic solvents; slightly soluble in ethanol. Solubility in organic solvents increases significantly with temperature.
Other properties: It is light-sensitive, and long-term exposure to strong light will cause decomposition and discoloration; it has no corrosiveness, is stable in dry air, and is not easy to volatilize; the refractive index is roughly estimated at 1.5200; it is a lipid-soluble antioxidant, widely present in cell membranes.
Chemical Properties
1. Oxidation-Reduction Activity: As a benzoquinone derivative, it has reversible oxidation-reduction properties, can accept and donate electrons, and plays a key role in the mitochondrial electron transport chain.
2. Stability: Stable under normal temperature and dry conditions; stable to weak acids and weak bases; unstable under strong light and high temperature (above 60°C), and easy to decompose; not easy to be oxidized by common oxidants in dark environment.
3. Reactivity: It can undergo addition, substitution and other reactions; the quinone ring can react with reducing agents to form hydroquinone; the isoprenyl side chain can undergo cyclization and oxidation reactions.
4. Incompatibility: Incompatible with strong oxidizing agents and strong reducing agents; avoid mixed storage to prevent chemical reactions; stable when mixed with common organic solvents and lipid-soluble substances.
Usage
1. Biochemical Research: As a key component of the mitochondrial electron transport chain, it is used for research on energy metabolism, oxidative stress and antioxidant mechanisms; used as a reference compound for ubiquinone content detection in biological samples.
2. Pharmaceutical Field: Used as an intermediate in the synthesis of antioxidant and anti-aging drugs; used in the research and development of drugs for mitochondrial diseases and cardiovascular diseases; used as a standard substance for drug quality control.
3. Food Industry: Used as an antioxidant and nutritional fortifier in health products and functional foods; added to dietary supplements to enhance antioxidant capacity and delay aging.
4. Industrial Field: Used as an antioxidant and stabilizer in the production of plastics, rubber and cosmetics; used in the synthesis of fine chemicals and lipid-soluble additives.
Storage
Store in a sealed container, keep away from light, heat and moisture; store in a cool, dry and well-ventilated warehouse, the recommended storage temperature is 2-8°C, and refrigerated storage is preferred. It should be stored separately from oxidants, reducing agents and other incompatible substances, and should not be mixed for storage; avoid long-term exposure to strong light to prevent decomposition and discoloration. The storage period can reach 1-2 years under proper storage conditions.
Safety Overview
Hazard Category: Low toxicity; Light-sensitive; May cause mild skin irritation (H315), mild eye irritation (H319); no obvious irritation to respiratory tract. It is for professional biochemical research, pharmaceutical manufacturing, food additive production and industrial use only; not for human consumption without purification.
Safety Precautions
1. Personal Protection: Wear protective gloves, safety goggles and dust mask when handling; avoid direct contact with skin, eyes and respiratory tract; ensure adequate ventilation in the operation area, and avoid inhalation of dust or aerosols.
2. Emergency Handling: If contact with skin, rinse thoroughly with plenty of flowing water for 5-10 minutes; if contact with eyes, rinse cautiously with water for several minutes (remove contact lenses if present) and continue rinsing, seek medical advice if discomfort occurs; if inhaled, move to fresh air immediately; if swallowed, call a poison center or doctor if feeling unwell.
3. Fire & Spill: Non-flammable; use dry powder, foam, carbon dioxide or water spray to put out fire in case of fire; if spilled, isolate the contaminated area, wear protective equipment, collect the spilled solid with dry and clean tools, put it into a sealed container for proper disposal, and avoid entering drains or water courses.
4. Disposal: Dispose of waste and packaging in accordance with local environmental regulations; do not discard at will; waste can be incinerated or treated as hazardous waste if it contains harmful substances.
