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

5-Bromo-2-chloro-3-pyridinecarboxylic acid features a pyridine ring bearing bromo and chloro substituents at the 5- and 2-positions, respectively, with a carboxylic acid group at the 3-position. This electron-deficient heterocycle serves as a key scaffold for medicinal chemistry applications, offering enhanced metabolic stability and tailored reactivity in cross-coupling transformations.

Application

5-Bromo-2-chloro-3-pyridinecarboxylic acid serves as a versatile building block for heterocyclic synthesis, enabling efficient construction of pyridine-based scaffolds in medicinal chemistry. Its orthogonal halogenation pattern facilitates selective cross-coupling reactions, while the carboxylic acid group supports direct derivatization or activation for amide and ester formation. The compound exhibits excellent bench stability and is compatible with standard purification methods, making it well-suited for iterative synthetic campaigns requiring functional group tolerance and predictable reactivity.
