Plasticizers are classified into two main categories primary and secondary. Primary plasticizers, such as dioctyl phthalate (DOP) and diisononyl phthalate (DINP), are typically used in large quantities and can significantly alter the properties of the base polymer. Secondary plasticizers, on the other hand, are added in smaller amounts and serve to enhance the performance of primary plasticizers or modify specific characteristics of the material. The choice of plasticizer depends on various factors, including cost, desired properties, and regulatory considerations.

APIs are essential in both prescription and over-the-counter medications, ranging from simple compounds to complex biologics. They can be derived from natural sources, synthesized chemically, or produced through biotechnological processes. The purity, potency, and quality of an API are crucial as they directly influence the safety and efficacy of the final drug product.

2. Industrial Applications

Being a colorless liquid with a mild odor, ethylene diformate is soluble in water, alcohol, and many organic solvents. This solubility is advantageous for formulating various products, particularly those that require a consistent mixture of components. Furthermore, EDF demonstrates stability under normal environmental conditions but can decompose upon exposure to high temperatures or specific catalysts.
