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
Excepted Quantity	$0.00
FedEx Limited Quantities Ground	$0.00
Hazmat Ground shipping	$50.00+
Inaccessible (Haz class 6.1 or 9), Domestic	$68.00+

Description

6-Bromo-2-chloro-3H-imidazo[4,5-b]pyridine is a heterocyclic scaffold featuring bromo and chloro substituents at strategic positions, enabling direct functionalization in cross-coupling reactions. This electron-deficient imidazopyridine serves as a key intermediate for constructing bioactive molecules in medicinal chemistry and agrochemical development.

Application

6-Bromo-2-chloro-3H-imidazo[4,5-b]pyridine serves as a versatile heterocyclic building block for medicinal chemistry and catalytic cross-coupling applications. The molecule’s dual halogenation pattern enables sequential functionalization via Pd-catalyzed coupling reactions, with the bromo group typically exhibiting higher reactivity than the chloro substituent. Its stability under standard reaction conditions and compatibility with diverse functional groups make it well-suited for constructing complex pharmaceutical scaffolds and kinase inhibitor cores in high-throughput synthesis workflows.
