Fosaprepitant Impurity N - Introduction
Dibenzyl phosphate, chemical formula C8H9PO4, is an organic phosphate ester compound. It is a colorless to pale yellow oily liquid with low volatility and high thermal stability.
Dibenzyl phosphate has a wide range of uses in the chemical industry. One of the most common uses is as a plasticizer to improve the flexibility and fluidity of polyvinyl chloride (PVC), making it suitable for the manufacture of plastic products, cables and synthetic leather. In addition, it can also be used as a light stabilizer, a modifier, a solvent for multilayer circuit boards, and an additive for detergents.
The preparation method of Dibenzyl phosphate generally adopts the esterification reaction of toluene and phosphoric acid. The specific preparation methods include direct esterification method, Ester exchange method and phosphoric acid hydrolysis method.
Because Dibenzyl phosphate is an organic phosphorus compound, it has certain toxicity and danger. During use, you need to pay attention to protective measures to avoid inhalation, contact with skin and eyes. If ingested or inhaled by mistake, seek medical attention immediately. At the same time, Dibenzyl phosphate should also be stored in a closed container, away from fire and high temperature environment, to avoid organic contact and leakage.
