Camphorquinone | 10373-78-1 FAQS

Camphorquinone is an organic compound derived from camphor, primarily used as a photoinitiator in dental materials. It initiates polymerization when exposed to visible light, making it essential in light-curable dental composites.​

The chemical formula of camphorquinone is C₁₀H₁₄O₂. It is also known as 2,3-bornanedione and has a molecular weight of 166.22 g/mol.​

Camphorquinone should be handled with care. It is a yellow crystalline solid that can cause skin and eye irritation upon contact. Proper personal protective equipment, such as gloves and safety glasses, should be used when handling this chemical.

Camphorquinone is widely used in dental materials as a photoinitiator. When exposed to blue light, it initiates the polymerization of resin-based composites, leading to the hardening of dental fillings and adhesives. Its effectiveness makes it a standard component in many dental restorative procedures.

Camphorquinone appears as a yellow crystalline powder with a melting point ranging from 198°C to 204°C. It is soluble in organic solvents like ethanol and ether but has limited solubility in water.
