Use:
As a basic raw material for fine chemical products, Nipagin esters, also known as hydroxybenzoate esters, have been widely used as preservatives in food, medicine, and cosmetics. They are also widely used in the preparation of various dyes, fungicides, color film, and various oil soluble colorants. The widely used new high-temperature resistant polymer, hydroxybenzoate polyester, is also used as the basic raw material.
