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.

Type	HazMat Fee

Description

4-Bromo-3-iodopyridine is a halogenated pyridine derivative featuring complementary reactive sites for cross-coupling transformations. The bromo group at the 4-position and iodo group at the 3-position enable sequential functionalization under palladium catalysis. This bifunctional architecture supports efficient diversification in medicinal chemistry and materials synthesis, particularly in constructing biaryl scaffolds with precise substitution patterns.

Application

4-Bromo-3-iodopyridine serves as a versatile building block in cross-coupling chemistry, enabling efficient access to substituted pyridine scaffolds. The orthogonal reactivity of bromo and iodo groups facilitates sequential functionalization via Pd-catalyzed couplings. Its bench-stable nature and compatibility with standard reaction conditions make it well-suited for medicinal chemistry and process development workflows.
