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

4-Bromo-5-chloropyridin-3-amine features a pyridine core functionalized with bromo and chloro substituents at the 4- and 5-positions, respectively, and a primary amine group at the 3-position. This electron-deficient heterocycle serves as a key building block in medicinal chemistry, enabling direct coupling reactions via its amine functionality and halogen sites for cross-coupling transformations under standard conditions.

Application

4-Bromo-5-chloropyridin-3-amine serves as a versatile building block in medicinal chemistry, enabling palladium-catalyzed cross-coupling reactions due to its orthogonal halogen reactivity. The bromo and chloro groups facilitate sequential functionalization, while the primary amine supports direct derivatization or protection. Its bench-stable nature and compatibility with standard reaction conditions make it ideal for constructing complex heterocyclic scaffolds in API development.
