Monoundecyl phthalate, with the CAS number 51622-03-8, is an ester derived from phthalic acid and undecanol. It is characterized by its relatively low volatility and high molecular weight, which contribute to its stability and performance in various applications. This compound is typically used as a plasticizer, enhancing the flexibility and durability of polymers, particularly in the production of flexible PVC and other plastic materials. Monoundecyl phthalate exhibits good compatibility with a range of polymers and can improve their processing characteristics. Additionally, it has a moderate to low toxicity profile, making it a preferable choice in applications where human exposure is a concern. The substance is generally stable under normal conditions but should be handled with care to avoid degradation. Its physical properties, such as solubility and melting point, can vary depending on the specific formulation and conditions. Overall, monoundecyl phthalate serves as an important additive in the plastics industry, contributing to the performance and longevity of various products.
