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-Chloro-5-iodopyridin-3-amine features a halogenated pyridine core with complementary chlorine and iodine substituents at the 2- and 5-positions, respectively, enabling selective cross-coupling reactions. The amine group at the 3-position provides a reactive handle for derivatization, while the molecule exhibits stability under standard bench conditions. This combination supports efficient access to complex heterocyclic architectures in medicinal chemistry and materials science applications.

Application

2-Chloro-5-iodopyridin-3-amine serves as a versatile building block for the construction of functionalized pyridine scaffolds in medicinal chemistry and materials science. Its complementary halogenation pattern enables sequential cross-coupling reactions via palladium catalysis, facilitating efficient access to biaryl and heterocyclic architectures. The compound exhibits good bench stability and is compatible with standard purification techniques, making it well-suited for iterative synthesis workflows in API development and library generation.
