Products Description of Phthalonitrile CAS#91-15-6

Aromatic nitrile compounds such as phthalonitrile are very important organic synthesis intermediates, which are widely used in medicines, pesticides, herbicides, insecticides, dyes, fragrances and natural products. For example, 2,4-dinitro-6-cyanoaniline, which can be used to make excellent bright blue diazo dyes, and lemon nitrile, an international new nitrile fragrance with a sharp and strong lemon-like aroma.
