Flavoxate is a medication primarily used to treat urinary incontinence and bladder spasms. However, during the manufacturing process, impurities may be introduced. These impurities can have negative effects on the medication's efficacy and safety, and therefore, it is important to monitor and control them. Some common flavoxate impurities include degradation products, residual solvents, and byproducts of synthesis. Proper identification and quantification of these impurities are crucial to ensure a high-quality final product.
