| Introduction | O-hydroxybenzonitrile, commonly known as salicylonitrile, is an off-white powdery solid with a pungent odor, A small amount can be affected by the breath, the smell is bitter; If a small amount of salicylic nitrile is opened in the state of no ventilation, the smell can be quickly spread throughout the room; Therefore, the operation must be done Protection Measure, reduce the irritation of the respiratory tract; Used as an intermediate of organic synthesis of bunilor, fungicide azoxystrobin intermediate. With a certain water solubility, Pka = 7.17, unstable to strong alkali and oxidant. |
| Use | O-hydroxybenzonitrile can be used as a pharmaceutical intermediate, which can be used as a synthetic drug for the treatment of hypertension and angina pectoris, the bactericide azoxystrobin can be synthesized, and in addition, a variety of perfumes and liquid crystal materials can be synthesized. An intermediate of Bunolol. used as pharmaceutical intermediates can be used in the synthesis of Bunolol. |
| reagent uses | O-hydroxybenzonitrile is used in the synthesis of a CDK / GSK-3 inhibitor and as a therapeutic agent for Alzheimer's disease. |
| production method | The product was prepared by condensing salicylaldehyde with hydroxylamine hydrochloride to produce salicylaldoxime, and then reacting with acetic anhydride and hydrolyzing. |
