Halofuginone is a synthetic quinazolinone alkaloid that has been studied for its potential as an anti-cancer and anti-fibrotic agent. Halofuginone impurities refer to the residual by-products or contaminants that are present during the production process of halofuginone. These impurities can impact the purity, efficacy, and safety of the final product, and therefore, must be carefully monitored and controlled during manufacturing. Analytical methods such as high-performance liquid chromatography
