Isopentyl pentyl phthalate (Cat No.: R053096) is a diester of phthalic acid formed by esterifying one carboxyl group with isopentyl alcohol and the other with pentyl alcohol. It is a hydrophobic, oily liquid commonly used as a plasticizer to enhance the flexibility and durability of polymers, particularly in PVC and other plastics. As a member of the phthalate family, it may also appear in coatings, adhesives, and personal care products. Due to potential environmental and health concerns, it is monitored for bioaccumulation and endocrine-disrupting effects.
