Description	Cyclopentanone has a wide range of downstream applications, spanning multiple fields such as fragrances, pharmaceuticals, pesticides, rubber synthesis, and electronic chemical solvents. Cyclopentanone is an important organic chemical raw material, used in the production of chemicals like bromocyclopentane and 1-cyclohexyl-5-(4-chlorobutyl)tetrazole. In the fragrance industry, cyclopentanone serves as a raw material for preparing novel fragrances such as jasmone, dihydrojasmone methyl ester, and white orchid ketone. In the pharmaceutical industry, it is a key raw material for synthesizing buspirone (an anti-anxiety drug), paclitaxel analogs (anticancer drugs), and the precursor of remdesivir (an anti-COVID-19 drug). Cyclopentanone exhibits excellent solubility for various resins and is widely used as a solvent in the rubber and electronics industries. High-purity cyclopentanone is employed in the cleaning of semiconductor photoresists, ensuring precision in chip manufacturing.
