2-Chloronicotinic Acid | Advanced Pyridine Intermediate | CAS 2942-59-8
Overview
2-Chloronicotinic Acid is a highly reactive, white to off-white crystalline powder. Structurally, it is a sophisticated pyridine derivative featuring both a carboxylic acid group and an activated chlorine atom in the ortho position. This dual-functionality makes it an exceptionally versatile building block in advanced organic synthesis. The activated chlorine is highly susceptible to nucleophilic substitution, while the carboxylic group enables robust esterification and amidation, unlocking complex synthetic pathways for blockbuster pharmaceutical APIs and next-generation agrochemicals.
Product Description
2-Chloronicotinic Acid is a highly reactive, white crystalline powder.

The activated chlorine is highly susceptible to nucleophilic substitution, while the carboxylic group enables robust esterification, unlocking complex synthetic pathways for blockbuster pharmaceutical APIs and next-generation agrochemicals.
At Shandong Yinglang Chemical Co., Ltd., established in 2011, we supply bulk commercial volumes of Ultra-High Purity 2-Chloronicotinic Acid to multinational pharmaceutical CDMOs and elite agrochemical formulators. Shipped globally as highly cost-effective Non-Dangerous Goods, our product is meticulously refined to eliminate trace heavy metals and moisture, guaranteeing flawless regioselectivity for your most demanding multi-step syntheses.
For complex API synthesis and high-efficiency herbicides, strict control of trace moisture and isomeric impurities is mandatory. Typical specifications:
| Purity (HPLC) | ≥ 99.0% |
|---|---|
| Moisture / Loss on Drying | ≤ 0.5% |
| Melting Point | 176°C - 180°C |
| Residue on Ignition | ≤ 0.1% |
- Pharmaceutical APIs (Anti-inflammatory): Serves as the critical starting material for synthesizing NSAIDs such as Pranoprofen and Niflumic Acid, utilized globally for pain management.
- Agrochemicals (Herbicides): The indispensable precursor for manufacturing sulfonylurea herbicides, most notably Nicosulfuron, a dominant herbicide for maize crops.
- Complex Heterocyclic Synthesis: Used by chemical CROs as a versatile building block to construct complex fused-ring systems in early-stage drug discovery.
- Specialty Dyes: Acts as an intermediate in the synthesis of advanced functional dyes.
In multi-step API synthesis (such as the production of Niflumic Acid), the initial nucleophilic displacement of the ortho-chlorine atom is the critical rate-determining step. Impure feedstocks laden with isomers or moisture will severely degrade reaction yields and generate toxic byproducts. Yinglang Chemical supplies High-Purity 2-Chloronicotinic Acid (≥ 99.0% by HPLC). By rigorously eliminating isomeric impurities and ensuring an active, uncompromised pyridine ring, we guarantee maximum regioselectivity and seamless scale-up reliability in your reactors.
As a stable crystalline powder, we offer cost-effective and highly secure bulk packaging for global ocean transit:
- 25 KG UN-approved Fiber Drums with thick double-layered PE inner liners (Tightly sealed to prevent moisture ingress).
- 25 KG Heavy-duty cartons with PE inner liners.
- Palletized loads available for continuous, large-scale industrial procurement.
