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-Bromo-5-fluoroisonicotinic acid features a strategically positioned bromine and fluorine at the pyridine ring's 2- and 5-positions, enabling selective cross-coupling and enhanced electronic tuning. This bench-stable derivative integrates readily into pharmaceutical intermediates, offering high reactivity under mild conditions with minimal side-product formation.

Application

2-Bromo-5-fluoroisonicotinic acid serves as a versatile building block in medicinal chemistry, enabling palladium-catalyzed cross-coupling reactions due to its orthogonal halogenation pattern. The bromo and fluoro substituents facilitate sequential functionalization, while the carboxylic acid group supports direct derivatization or activation for amide bond formation. Its bench-stable crystalline form simplifies handling and purification, making it well-suited for iterative synthesis of heterocyclic scaffolds and API intermediates.
