The IUPAC name of DI-n-Nonyl phthalate is dinonyl benzene-1,2-dicarboxylate. With the CAS registry number 84-76-4, it is also named as 1,2-Benzenedicarboxylic acid, dinonyl ester; Bisoflex DNP. The product's categories are functional materials; phthalates (plasticizer); plasticizer; gas chromatography; packed GC; stationary phases. It is clear yellow-brown oily liquid which is used as plasticizer for PVC. In addition, DI-n-Nonyl phthalate is flammable by fire, heat and oxidants. And it can be hydrolyzed by strong mineral acids and strong alkalis. It is also moderately toxic by ingestion. This chemical must be stored in a tightly closed container which is placed in a cool, dry, well-ventilated area away from incompatible substances.

The DI-n-Nonyl phthalate is an ester. Esters react with acids to liberate heat along with alcohols and acids. Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products. Heat is also generated by the interaction of esters with caustic solutions. Flammable hydrogen is generated by mixing esters with alkali metals and hydrides.
