With its molecular formula C8H4N2O, this molecule combines an aromatic benzene ring with two nitrile (-CN) groups and one hydroxyl (-OH) group, bestowing upon it a unique reactivity profile. The strategic placement of these functional groups makes it an invaluable building block for chemists aiming to create complex molecules for various industries. NINGBO INNO PHARMCHEM CO.,LTD provides this essential compound, ensuring high purity for critical research and industrial applications.

Delving into its chemical properties, 5-Hydroxyisophthalonitrile typically presents as a white to off-white crystalline powder. Its relatively high melting point, around 266°C, indicates a stable solid structure. This stability is advantageous during handling and storage, as well as in chemical reactions that may involve elevated temperatures. The presence of the nitrile groups lends electron-withdrawing character to the aromatic ring, influencing its reactivity in electrophilic and nucleophilic substitution reactions. The hydroxyl group, being electron-donating, also plays a crucial role, offering a site for further derivatization, such as esterification or etherification, and can participate in hydrogen bonding, influencing solubility and crystalline structure.

The synthesis of 5-Hydroxyisophthalonitrile often involves multi-step processes starting from readily available aromatic precursors. While specific industrial routes may vary, they generally focus on introducing the nitrile and hydroxyl functionalities onto a benzene core through established chemical transformations. These synthetic pathways are optimized by manufacturers like NINGBO INNO PHARMCHEM CO.,LTD to achieve high yields and exceptional purity, minimizing side products and ensuring the intermediate is fit for demanding applications.

The applications of 5-Hydroxyisophthalonitrile are diverse and impactful. In the realm of organic synthesis, it is a sought-after intermediate for the creation of pharmaceuticals.
