1,2-Benzenedicarboxylic acid, di-C7-11-branched and linear alkyl esters

Description:
1,2-Benzenedicarboxylic acid, di-C7-11-branched and linear alkyl esters, commonly known as diisononyl phthalate (DINP), is a chemical compound primarily used as a plasticizer in the production of flexible polyvinyl chloride (PVC) and other polymers. This substance features a phthalate backbone with two carboxylic acid groups esterified with branched and linear alkyl chains, specifically those ranging from 7 to 11 carbon atoms in length. The branched and linear nature of the alkyl groups contributes to its effectiveness as a plasticizer, enhancing the flexibility, durability, and workability of plastic materials. Additionally, DINP is characterized by its relatively low volatility and good thermal stability, making it suitable for various applications, including toys, flooring, and automotive components. It is important to note that, like other phthalates, DINP has been subject to regulatory scrutiny due to potential health and environmental concerns, leading to ongoing research into its safety and alternatives in industrial applications.
