Global 4-Hydroxydiphenylamine Market Strategic Research Report

Scope of the Report

The global 4-Hydroxydiphenylamine market size is predicted to grow from US$ 551 million in 2025 to US$ 963 million in 2032; it is expected to grow at a CAGR of 8.5% from 2026 to 2032.

p-Hydroxydiphenylamine (p-HDI) is an organic compound with aromatic amino and hydroxyl groups. It is an important antioxidant and anti-aging agent, commonly used in the rubber, plastics, and lubricant industries to prevent oxidative degradation of materials under conditions of heat, oxygen, and ultraviolet radiation, thus extending product lifespan. p-HDI provides excellent antioxidant properties through the hydroxyl and amino groups in its chemical structure, making it widely used in industrial production and material protection.

The upstream of the p-HDI industry chain mainly includes the supply of aniline, phenols, and related chemical raw materials, while also involving basic fine chemical processes such as nitration and reduction, as well as related chemical equipment. The midstream involves the synthesis, refining, and production of p-HDI at different purities, and is the core link of the industry chain. Downstream applications are wide-ranging, including rubber antioxidants, dye intermediates, pharmaceuticals, and fine chemical products. It enters the market through chemical distributors or direct industrial users. The entire industry chain is highly sensitive to raw material costs, synthesis process efficiency, and environmental policies.

In 2025, the average price of p-HDI was US$2,980 per ton, with sales volume reaching 188.9 k tons.

p-Hydroxydiphenylamine is a key aromatic chemical intermediate widely used in areas such as rubber antioxidants, dyes, and pharmaceutical intermediates. It enjoys stable market demand and diverse downstream applications. With increasingly stringent environmental regulations and growing demand for high-value fine chemicals, the industry is developing towards high purity, green synthesis, and high-performance applications. It continues to hold significant strategic value and development potential in the market for chemical raw materials and functional intermediates.
