PRODUCT INTRODUCTION
Description
2-Chloronicotinic acid as a pyridine derivative is receiving much attention because of its effective application as an essential precursor in synthesising pesticides and pharmaceuticals. It is extensively used to synthesise the new high-efficiency herbicides nicosulfuron and diflufenican, which have low toxicity, high biological activities, broad-spectrum activity, and outstanding environmental compatibility. It is also a key building block for new endogenous fungicides (pyridinimide), antimicrobial agents and anticancer drug intermediates (2-chloropyridine-3-carbonyl-containing heterocyclic compounds), new non-nucleoside reverse transcriptase inhibitors, HIV reverse transcriptase inhibitors (nevirapine), pesticides, and pharmaceutical intermediates. Among these, nicosulfuron is an efficient corn herbicide, and the market demand is increasing yearly.
