Industrial Applications
Diethyl Phthalate is primarily employed as a synthetic intermediate in the manufacture of anticoagulant rodenticides, including Chlorophacinone (CAS 3691-35-8), Pindone (CAS 83-26-1), and Diphacinone (CAS 82-66-6). Its reliable reactivity and consistent purity make it suitable for controlled multi-step organic syntheses in regulated agrochemical production environments. It is not intended for use in consumer-facing formulations such as cosmetics or nutraceuticals.
For industrial clients, we offer this compound in standard 25 kg drums, with custom packaging available upon request. Storage should be in a cool, dry, and well-ventilated area with containers tightly sealed to maintain stability and prevent contamination.
