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-4-chloropicolinic acid is a halogenated picolinic acid derivative featuring bromine at the 5-position and chlorine at the 4-position of the pyridine ring. This electron-deficient heterocycle serves as a key building block in medicinal chemistry, enabling direct coupling reactions for synthesizing bioactive compounds. The dual halogenation enhances reactivity in cross-coupling processes, while the carboxylic acid group facilitates derivatization and conjugation.

Application

5-Bromo-4-chloropicolinic acid serves as a versatile building block in medicinal chemistry and agrochemical synthesis, enabling direct incorporation of halogenated pyridine motifs into complex scaffolds. Its dual halogen substituents facilitate cross-coupling reactions such as Suzuki-Miyaura and Stille coupling, while the carboxylic acid group supports amide formation and derivatization. The compound exhibits good bench stability and is readily purified by recrystallization, making it well-suited for reproducible scale-up in industrial R&D workflows.
