Properties and stability
Avoid contact with oxidants, acidic substances, and water.
Storage method
Store in a cool, ventilated warehouse. Keep away from fire, heat and water sources. They should be stored separately from oxidants and acidic substances, and avoid mixed storage. Keep sealed. Use explosion-proof lighting and ventilation facilities. It is prohibited to use mechanical equipment and tools that are prone to sparks. The storage area should be equipped with emergency release equipment and suitable containment materials.
Synthesis method
It is prepared from pyridine as raw material or by reduction with the corresponding pyridine carboxaldehyde, or by catalytic hydrogenation of the corresponding pyridine carboxylic acid ester.
Purpose
Used on surrounding blood vessel walls to dilate blood vessels and lower cholesterol. Used for acral arterial spasm, acrocyanosis, chilblains, migraine, retinal vascular embolism, etc.
