DL-Camphorquinone (CAS 10373-78-1) is a visible-light photoinitiator, a yellow crystalline alpha-diketone with 99% purity. It features an absorption maximum at 468 nm, ideally matching blue LED dental curing lights, and initiates polymerisation in under 20 seconds. S.Nihar Exports, an ISO 9001:2015 certified supplier, provides DL-Camphorquinone with a Certificate of Analysis (COA).
Chemical Profile and Characteristics
DL-Camphorquinone (CAS 10373-78-1) is a yellow crystalline alpha-diketone identified by its 99% purity. As a visible-light photoinitiator, it exhibits an absorption maximum at 468 nm, which makes it an ideal match for blue LED dental curing lights operating between 430-490 nm. Its camphor-derived structure contributes to excellent solubility within methacrylate monomer systems.
Primary Applications
DL-Camphorquinone functions as a standard photoinitiator in dental composite resins and bonding agents, where it facilitates polymerisation in under 20 seconds. Beyond its primary use in dentistry, it is also applied as a photoinitiator in 3D printing photopolymer resins (SLA/DLP), UV-curable coatings and adhesives, photopolymer optical waveguides and sensors, and visible-light initiated holographic recording materials. Typical usage concentrations range from 0.1-1.0 wt% and generally require a co-initiator such as DMAEMA or EDMAB.
