==============================================================================
Purpose:
It is mainly used as a preservative and fungicide in food, cosmetics, pharmaceuticals, and feed, with antibacterial and antioxidant effects.
As a bacteriostatic preservative in pharmaceuticals and cosmetics, its preservative effect is greater than that of nipagin ethyl ester.
Used as organic synthesis reagents and pharmaceutical industry raw materials.
It can be mixed with other preservatives such as methylparaben to enhance its antibacterial effect.
==========================================================
Synthesis route: It is prepared by esterification reaction of p-hydroxybenzoic acid and n-propanol under acidic conditions (such as sulfuric acid or cation exchange resin catalysis). After the reaction, the finished product is obtained through steps such as neutralization, washing, decolorization, and recrystallization.
