4-Amino-2-chloropyridine Chemical Properties,Uses,Production

Description

4-Amino-2-chloropyridine is an important pharmaceutical and pesticide intermediate. It can synthesize N-(2-chloro-4-pyridyl)urea regulators that promote plant growth. It is also a key substance in the synthesis of KT-30 (Forchlorfenuron, IUPAC name N-(2-chloro-4-pyridyl)-N'-phenylurea). KT-30 is a highly active cytokinin, which has the biological activity of promoting tissue growth, promoting bud development and green preservation; it has an effect of increasing yield on apple, pear, grape, peach and other fruit crops.
4-Amino-2-chloropyridine itself can also be used as a pesticide alone, and has high activity against various pathogens such as rust, powdery mildew, rice blast, and apple downy mildew. 4-Amino-2-chloropyridine and its pharmaceutical and pesticide intermediates have the advantages of high biological activity, low toxicity, long-lasting period and easy degradation in the environment, so they have broad application prospects in agricultural production.

Chemical Properties
