Phthalic acid is a common organic compound used in the production of various consumer goods. Unfortunately, this compound is often contaminated with impurities that can affect its quality and purity. These impurities can include heavy metals, residual solvents, and other organic compounds that can be harmful to human health or interfere with the intended use of the product. Therefore, it is important to carefully monitor and control the production process to minimize the presence of these impurities and ensure the safety and efficacy of products that contain phthalic acid.
