What is DL-CAMPHORQUINONE?

Chemical properties

YELLOW FINE CRYSTALLINE POWDER

The Uses of DL-CAMPHORQUINONE

initiator for visible-light-cured dental acrylic-composite materials.

The Uses of DL-CAMPHORQUINONE

Camphorquinone derivative (i.e. carboxylated camphorquinone) is used as visible-light photoinitiator in biomedical applications. It is also used in dentistry and is often used in conjunction with hydrogen donating amine.

The Uses of DL-CAMPHORQUINONE

CQ-amines are used as a photo initiators for free radical polymerization. CQ was used as an initiator in the preparation of silver nanoparticle/silica/ polymer nanocomposites. Photopolymerization kinetics of dimethacrylates were studied using the CQ/amine initiator system.

Definition

ChEBI: Bornane-2,3-dione is a bornane monoterpenoid that is bicyclo[2.2.1]heptane substituted by methyl groups at positions 1, 7 and 7 and oxo groups at positions 2 and 3. It is a bornane monoterpenoid and a carbobicyclic compound.

General Description

Camphorquinone (CQ) absorbs UV radiation in the region of 200-300nm due to the Π?Π^* transition and visible light (400-500nm) due to the n, Π* transition of the α-dicarbonyl chromophore.

Purification Methods

Purification is the same as for above enantiomers. [Huckel & Fichtig Justus Liebigs Ann Chem 628 81 1962, Evans et al. J Chem Soc 137 1939, Beilstein 7 I 325.]
