o-Phenylenediamine

oPhenylenediamine (CAS: 95545) is a highlyactive aromatic amine finechemical intermediate. Boasting excellent chemical reactivity and stable physicochemical properties, it is widely applied in pharmaceuticals, agrochemicals, dyes, newtype materials, analytical chemistry and other fields, serving as an indispensable core raw material for the modern finesynthesis industry. It appears as white to lightbrown flaky crystals with high purity, low impurities and strong batchtobatch stability, fully meeting the requirements of various highend synthesis processes.

This product features wide application coverage and prominent industrial value. In the pharmaceutical sector, oPhenylenediamine acts as a key intermediate for synthesizing benzimidazole and quinoxalinebased pharmaceuticals. It is mostly used in the production of antibacterial, antiinflammatory and anthelmintic APIs. With few side reactions and high synthetic conversion rate, it effectively improves the quality of finished pharmaceutical products. In the agrochemical industry, it is utilized to manufacture intermediates for highefficiency fungicides and insecticides, and constitutes an essential basic raw material for the R&D and production of ecofriendly pesticides. In the dye industry, it is a core synthetic feedstock for sulfur dyes, azo dyes and colorants. It delivers stable color development and outstanding color fastness, well suited for printingdyeing and cosmetic pigment sectors.

Meanwhile, oPhenylenediamine can be used as epoxy resin curing agent, polymer crosslinking agent and biochemical analytical reagent. It performs excellently in newmaterial modification and chemical testing to satisfy diverse industrial production requirements.
