Nitrogen-containing Heterocycles

Pyridine series includes methylpyridine, cyanopyridine, chloropyridine, nicotinic acid, nicotinamide and other derivatives. It is mainly used as intermediate for pesticide insecticides, herbicides and fungicides, synthetic raw materials for pharmaceutical API, nutritional feed additives, industrial solvents, rubber additives, dye intermediates and lithium battery electrolyte additives.

Pyrimidine series includes chloropyrimidine, aminopyrimidine, fluorouracil, cytosine, uracil and other derivatives. Widely used in synthesis of anti-tumor drugs, antiviral drugs and sulfonamides pesticides, agricultural fungicides, herbicides, plant growth regulators, biological nucleic acid raw materials and fine chemical synthetic intermediates.

Used as synthetic raw materials for medical anesthetics, antihistamines and psychotropic drugs, intermediates for agricultural insecticides and fungicides, strong alkaline catalysts for organic synthesis, epoxy resin curing agents, rubber additives and solvent extractants.
