CAS 117-81-7: Dioctyl phthalate

Description: Dioctyl phthalate (DOP), with the CAS number 117-81-7, is a colorless to pale yellow liquid that is primarily used as a plasticizer in the production of flexible polyvinyl chloride (PVC) and other polymers. It enhances the flexibility, durability, and workability of plastic materials. DOP is characterized by its low volatility, good thermal stability, and resistance to water and UV light, making it suitable for various applications, including coatings, adhesives, and sealants. The substance has a relatively high molecular weight and a low freezing point, which contributes to its liquid state at room temperature. However, DOP is also known for its potential environmental and health concerns, as it can act as an endocrine disruptor and has been subject to regulatory scrutiny. Its use has been restricted in certain applications, particularly in toys and childcare products, due to concerns about its effects on human health and the environment. Overall, while dioctyl phthalate is an effective plasticizer, its safety profile necessitates careful consideration in its applications.
