HazMat Fee

An item is classified as a dangerous good if our website displays Hazardous Material (HazMat) information for it. There is a HazMat shipping fee for each item that qualifies as a dangerous good, except in the following scenarios:

The shipment is processed through FedEx Ground under the Limited Quantity option.

Each bottle is packed as an Excepted Quantity, with a maximum of 1g for items in class 6.1 packing group I or II, and up to 25g for all other hazardous materials.

If shipping is charged to your FedEx account, the HazMat fee will be billed directly by the courier. Otherwise, the fee will be included on your invoice. To help you avoid the HazMat fee, we can package a 5g order of a class 6.1 packing group I or II material as five separate 1g units, and a 100g order of any other dangerous good as four 25g units. This packaging adjustment will be made unless you instruct otherwise on your purchase order. Below, you will find the fee schedule from FedEx for handling hazardous materials.

Description

2,5-Dichloronicotinic acid is a sterically hindered, electron-deficient heterocyclic carboxylic acid featuring two chlorine substituents at the 2- and 5-positions of the pyridine ring. This configuration enhances its stability and reactivity in coupling processes, enabling efficient incorporation into pharmaceutical intermediates and functional materials under standard conditions.

Application

2,5-Dichloronicotinic acid serves as a versatile building block in medicinal chemistry and agrochemical synthesis, enabling efficient access to substituted pyridine scaffolds. Its dual chloro substituents facilitate palladium-catalyzed cross-coupling reactions and nucleophilic aromatic substitution, while the carboxylic acid group supports direct derivatization or activation for amide bond formation. The compound exhibits good bench stability and facilitates straightforward purification, making it well-suited for scalable synthetic workflows.
