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-Chloro-3-iodopyridine is a halogenated pyridine derivative featuring complementary reactive sites for cross-coupling transformations. The chlorine and iodine substituents enable sequential functionalization under palladium catalysis, offering precise control in building complex heterocyclic architectures. This compound serves as a key intermediate in medicinal chemistry and materials synthesis, combining high reactivity with bench-stable handling.

Application

4-Chloro-3-iodopyridine serves as a versatile bifunctional building block in cross-coupling chemistry, enabling sequential functionalization at the 3- and 4-positions of the pyridine ring. The chlorine moiety undergoes palladium-catalyzed coupling with boron, tin, or zinc reagents, while the iodide facilitates orthogonal Suzuki, Stille, or Negishi reactions. Its bench-stable nature and compatibility with diverse reaction conditions make it ideal for constructing complex heterocyclic scaffolds in medicinal chemistry and materials science.
