Product Details

3,3′-Diaminobenzidine (DAB) is a core monomer for high-performance materials such as PBI and an important pharmaceutical intermediate, widely used in cutting-edge fields like aerospace and defense. Our company has long been committed to the R&D and production of DAB, leveraging a fully integrated industrial chain and large-scale production capacity to become a domestic industry benchmark, thereby supporting downstream industries worldwide.
In terms of production capacity, the company is the only domestic enterprise to have achieved large-scale DAB production, with an annual capacity of 100 tons. This enables it to meet global bulk demand, reduce customers’ procurement costs and supply‑chain risks, and offers flexible expansion capabilities, giving it a distinct cost and efficiency advantage over small‑batch pilot producers.
Technically, the company places R&D at its core, optimizes synthetic routes, and employs highly efficient catalytic reduction technologies to enhance product purity, thereby addressing the longstanding issue of DAB’s susceptibility to oxidation. It also offers customized solutions tailored to downstream requirements, with key performance indicators that lead the industry.
The product boasts high purity, excellent color, and robust antioxidant properties, meeting the stringent requirements of the PBI and pharmaceutical industries. It complies with pharmaceutical GMP standards, and end-to-end quality control ensures a leading product pass rate.
In the market, our products are exported to numerous countries and regions worldwide, breaking international monopolies while supporting domestic import substitution. Our dedicated service team ensures rapid responses to customer needs, driving continuous growth in market share. Looking ahead, the company will remain committed to strengthening its position and striving to become a global leader in the DAB industry.
