The market demand for 2,3-dichloropyridine is becoming increasingly urgent, and domestic related new and under-construction projects are increasing.

2,3-Dichloropyridine appears as white to slightly beige crystalline powder. As an important intermediate, 2,3-dichloropyridine is widely used in pesticides, medicines, fine chemicals and other fields.

The upstream products of 2,3-dichloropyridine include 2-chloro-3-aminopyridine, 2,3,6-trichloropyridine, 2-chloropyridine, 3-aminopyridine, etc., and the downstream products include 2-amino-3- Chloropyridine, (3R)-1-(3-chloropyridin-2-yl)-3-methylpiperazine, 2,3-dichloropyridine-4-boronic acid, etc. 2,3-Dichloropyridine is an important raw material for the synthesis of many new pesticides such as chlorantraniliprole. In recent years, as environmental protection requirements have become increasingly stringent, the application scope of new pesticides has been expanding. 2,3-Dichloropyridine The market demand for pyridine was subsequently released.

According to the “2023-2028 China 2,3-dichloropyridine industry market in-depth research and development prospect forecast report》shows that in order to meet the expanding market demand, my country’s 2,3-dichloropyridine-related projects have increased. Currently, companies such as Red Sun, Jiangsu Chaoyue Chemical, Jiujiang Shanshui Technology, and Yichang Hengyou Chemical all have 2,3 -Dichloropyridine related construction projects.

Chlorantraniliprole is a new type of o-carbamylinobenzamide insecticide, which has the characteristics of low toxicity, high efficiency, good activity and broad insecticidal spectrum. In recent years, the global chlorantraniliprole market has experienced strong growth momentum, with global sales reaching approximately US$2.45 billion in 2022. At present, my country’s chlorantraniliprole industry is in a production capacity expansion period. Since 2020, the total declared production capacity of chlorantraniliprole has been around 100,000 tons. my country’s chlorantraniliprole-related companies include Red Sun, Lier Chemical, Yangnong Chemical, Youdao Chemical, Hailier, etc.

2,3-Dichloropyridine is one of the important intermediates in the synthesis process of chlorantraniliprole. With the expansion of chlorantraniliprole production capacity, the market demand for 2,3-dichloropyridine is becoming increasingly strong. The synthesis methods of 2,3-dichloropyridine include 2,3,6-trichloropyridine reduction method, 2-chloropyridine synthesis method, 3-chloropyridine synthesis method, 3-aminopyridine synthesis method, etc. In recent years, thanks to technological advancements, the price of 2,3-dichloropyridine products has declined.

The traditional 2,3-dichloropyridine synthesis process has problems such as poor chlorination selectivity, large amounts of by-product salts, complex ingredients that are difficult to handle, and low production yields. In the context of increasingly stringent environmental protection requirements and the release of demands for cost reduction and efficiency improvement, The market is increasingly urgent for new, safe, green, and easy-to-large-scale production of 2,3-dichloropyridine synthesis methods. In 2023, the China Pesticide Industry Association issued a “Solicitation for 2,3-dichloropyridine green synthesis technology” announcement for scientific research institutions, universities, technical communities, enterprises, innovation teams and other entities.

Industry analysts said that the patented compound of chlorantraniliprole has expired in August 2023. With the increase in layout companies, With the implementation of industrialized equipment, the scale of the chlorantraniliprole industry will be further expanded. 2,3-Dichloropyridine is the core raw material for the production of chlorantraniliprole. With the expansion of chlorantraniliprole production capacity, the 2,3-dichloropyridine market has broad development space. At the same time, as environmental protection supervision becomes increasingly strict, it has 2 , Enterprises with green and efficient production technology of 3-dichloropyridine will have more development advantages.
