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

3-Bromo-2-chloro-5-nitropyridin-4-amine features a pyridine core functionalized with bromo, chloro, and nitro groups at key positions, enabling strategic coupling in cross-coupling reactions. The electron-deficient ring enhances reactivity in palladium-catalyzed transformations. This bench-stable derivative integrates readily into complex heterocyclic scaffolds for pharmaceutical and agrochemical development.

Application

3-Bromo-2-chloro-5-nitropyridin-4-amine serves as a versatile building block for heterocyclic synthesis, enabling palladium-catalyzed cross-coupling reactions due to its bromine and amine functionalities. The nitro group provides a handle for selective reduction or further functionalization, while the chloro substituent offers orthogonal reactivity. Its bench-stable nature and compatibility with standard reaction conditions facilitate efficient assembly of complex pyridine-based scaffolds in medicinal chemistry and materials science applications.
