Discontinued product3-(4-Methylbenzylidene)camphor
CAS:3-(4-Methylbenzylidene)camphor is a chemical compound that has two isomers, alpha and beta. It can be found in biological samples, such as human urine or wastewater, and can be used for the treatment of skin cancer. 3-(4-Methylbenzylidene)camphor is prepared by extraction from a dry sample with an organic solvent. The extraction process requires a hydroxyl group to react with the dry sample and create a liquid. The resulting liquid is then evaporated to leave behind the extract. The kinetic data of 3-(4-Methylbenzylidene)camphor was determined by measuring its rate of reaction with an analytical method. The rate of reaction increased as the concentration increased to a constant value at high concentrations, which suggests that it may have some occlusive properties in humans due to its tendency to bind to plasma proteins.
