China and India are the leading exporters of 4-Hydroxybenzoic acid (CAS 99-96-7), collectively accounting for the majority of global export volume, while the United States, Germany, and South Korea represent the largest importers. Trade flows have remained relatively stable over the past three years, with modest growth in imports by Southeast Asian countries and continued price sensitivity reflected in regional variations in 4-Hydroxybenzoic acid prices.
4-Hydroxybenzoic acid is a white to off-white crystalline solid with a faint, characteristic odor; it has a melting point of approximately 213–217 °C and is only slightly volatile under ambient conditions. It is an aromatic organic compound classified as a phenolic carboxylic acid and serves primarily as a chemical intermediate. Its principal industrial use is in the synthesis of parabens—alkyl esters widely employed as preservatives in pharmaceuticals, cosmetics, and food products. It is also utilized in the production of liquid crystal polymers, heat-resistant resins, and certain dyes and UV absorbers. Key application sectors include personal care formulations, pharmaceutical manufacturing, and high-performance polymer synthesis.
p-Hydroxybenzoic acid is of significant commercial importance. The most familiar application is the use of several of its esters as preservatives, known as parabens. Also of interest is the use in liquid crystal polymer applications.
