o-Phenylenediamine (OPD), with CAS number 95-54-5, is a fundamental organic chemical that plays a pivotal role as an intermediate in numerous synthetic processes. Its unique chemical structure and reactivity make it an indispensable component in the manufacturing of a wide array of products, from life-saving pharmaceuticals to vibrant pigments. NINGBO INNO PHARMCHEM CO.,LTD. is dedicated to providing high-quality OPD to meet the diverse needs of the global market.

Chemically, o-Phenylenediamine is an aromatic diamine characterized by its two amine groups attached to adjacent carbon atoms on a benzene ring. It typically presents as a white or off-white crystal or flake, with a melting point in the range of 100-104°C and a boiling point of approximately 252-258°C. Its solubility in water, especially hot water, further enhances its utility in various chemical reactions and formulations. Understanding these physical and chemical properties is crucial for effective handling and application. If you're considering where to purchase o-phenylenediamine, NINGBO INNO PHARMCHEM CO.,LTD. offers reliable sourcing.

The synthesis of o-Phenylenediamine often involves the reduction of 2-nitroaniline, which is itself derived from the nitration of chlorobenzene followed by ammonolysis. This multi-step process requires precise control to ensure high purity, a factor that NINGBO INNO PHARMCHEM CO.,LTD. prioritizes. The availability of this key intermediate at a competitive price for o-phenylenediamine directly impacts the cost-effectiveness of downstream products.

The applications of o-Phenylenediamine are remarkably broad. In the realm of agrochemicals, it serves as a critical o-phenylenediamine intermediate for the synthesis of fungicides and herbicides. These agricultural chemicals are essential for crop protection, ensuring higher yields and better quality produce. The effectiveness of these pesticides is directly linked to the quality of the OPD used in their manufacture. Therefore, sourcing from a reputable o-phenylenediamine manufacturer like NINGBO INNO PHARMCHEM CO.,LTD. is vital.

In the pharmaceutical sector, OPD functions as an essential o-phenylenediamine pharmaceutical intermediate.
