Tigogenin is a steroidal sapogenin, commonly used in the production of steroids and hormones. However, during its synthesis process, impurities may occur, which can affect the purity and quality of the final product. These impurities can include residual solvents, degradation products, and other organic and inorganic contaminants. Their presence can have negative effects on the safety and efficacy of tigogenin, making it important to monitor and control the impurity levels during its production.
