Description

(1R)-(-)-Camphorquinone CAS NO 10334-26-6 is a high-purity, optically active diketone derivative of camphor, serving as a critical photoinitiator and chiral building block. Its primary commercial value lies in its exceptional efficiency in initiating free-radical polymerization upon exposure to visible blue light. This compound is essential for manufacturers in the dental materials, advanced coatings, and fine chemical synthesis sectors who require reliable, high-performance photoinitiators with specific stereochemistry.

Application

• Dental Composites and Adhesives: The predominant application is as a photoinitiator in light-curable dental restorative materials, sealants, and cements.
• Advanced Polymer Coatings: Used in UV/visible light-curable inks, varnishes, and protective coatings for electronics and industrial finishes.
• Optical Resins and Lenses: Employed in the production of precision optical components and eyeglass lenses requiring controlled curing.
• 3D Printing (Stereolithography): Acts as a key component in photopolymer resins for high-resolution additive manufacturing.
• Chiral Synthesis: Utilized as a versatile starting material or catalyst in asymmetric synthesis for pharmaceuticals and agrochemicals.
• Adhesives and Encapsulants: Facilitates rapid curing in specialty adhesives and potting compounds used in electronics assembly.
