Diisopentyl phthalate(CAT: R053092) is a phthalate ester formed by the reaction of phthalic acid with isopentyl alcohol, resulting in a diester with two branched alkyl chains. It is a colorless, oily liquid commonly used as a plasticizer, imparting flexibility and durability to polymers such as PVC, rubber, and synthetic resins. Its branched isopentyl groups provide low volatility and improved performance in high-temperature and industrial applications. Diisopentyl phthalate is also studied in environmental science due to its persistence and potential as a contaminant. Its physicochemical properties make it valuable in materials processing, though its use may be regulated due to health and environmental concerns.
