465-29-2 Usage

General Description

DL-Camphorquinone, often abbreviated as CQ, is a yellow crystalline solid and a type of ketone that is typically derived from the natural compound camphor. Its primary use is in the polymer industry as a photoinitiator, where it begins the polymerization process when exposed to light. In dentistry, it is used in light-cured dental fillings and restorative materials to encourage the hardening process. Despite its widespread use, exposure to DL-Camphorquinone can cause skin and eye irritation, and prolonged inhalation may result in harm. Therefore, it must be handled with care, typically through the use of gloves and eye protection.

Check Digit Verification of cas no

The CAS Registry Mumber 465-29-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,6 and 5 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 465-29:
(5*4)+(4*6)+(3*5)+(2*2)+(1*9)=72
72 % 10 = 2
So 465-29-2 is a valid CAS Registry Number.

Novel synthetic method of camphorquinone

-

Paragraph 0018-0019, (2020/05/30)

The invention relates to a novel synthetic method of camphorquinone, which is a method for preparing camphorquinone from camphor in the presence of a catalyst. The invention further provides a methodfor preparing camphorquinone, which can effectively reduce the toxicity of the used catalyst and reflect the harm to the environment, and ensures a high yield of the reaction while simplifying the process flow. According to the method, clean energy microwave irradiation instead of conventional energy is utilized, so that the pollution of the reaction to the environment is greatly reduced while thereaction yield is ensured, and the purpose of green chemistry is met.

Method for producing camphorquinone by taking byproduct generated in camphor synthesis process as raw material

-

Paragraph 0050; 0051, (2019/09/14)

The invention provides a method for producing camphorquinone by taking a byproduct generated in the camphor synthesis process as a raw material, belonging to the technical field of organic synthesis.The byproduct 3-camphene ester generated in the synthesis process of camphor is used as a starting material to prepare high-purity camphorquinone through refining, saponification, dehydrogenation, condensation, hydrolysis and recrystallization steps. The method has the beneficial effects that the value of the byproduct generated in the camphor synthesis process is used, industrial wastes are reduced, wastes are changed into valuables, environmental pressure is reduced, a brand-new path for the synthesis of the camphorquinone is provided, no heavy metals are used in all process steps, truly nontoxic chemical synthesis of the camphorquinone is realized, and the method is an economic and environment-friendly production process.

Selectivity of the complexation reactions of four regioisomeric methylcamphorquinoxaline ligands with gold(III): X-ray, NMR and DFT investigations

, p. 137 - 149 (2016/01/15)

Reported are the synthesis, spectral and structural characteristics of new quinoxaline-related regioisomeric ligands L1-L4 (1,x,11,11-tetramethyl-1,2,3,4-tetrahydro-1,4-methanophenazine, x = 7, 8, 9 and 6, respectively) and their mononuclear Au(III) complexes (1-4). Fusion of the camphor moiety to the quinoxaline core made two N-atoms of quinoxaline nonequivalent while the introduction of a methyl-substituent at positions 6-9 enabled a tuning of coordination properties of L1-L4. Gold(III) complexes 1-4 and ligands L1-L4 have been studied in detailed by 1D and 2D NMR and the structures of 1-4 have been determined by X-ray crystallography. The results of these analyses revealed a regiospecific coordination of Au(III) to the sterically less hindered N-5 atom (spatially close to the non-substituted bridgehead carbon) of L1-L3, and to N-10 (spatially close to the methyl-substituted bridgehead carbon) of L4. The results of DFT calculations shed light on disparate coordination modes of L1-L4 toward the AuCl3 fragment and explain formation of single coordination products in high yield.
