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

1H-Imidazo[4,5-b]pyridine is a rigid, electron-rich heterocycle featuring a fused imidazole-pyridine core. This scaffold exhibits strong π-conjugation and planarity, enabling effective integration into advanced materials and pharmaceutical scaffolds. The nitrogen-rich framework enhances solubility in polar solvents and supports metal coordination. Its bench-stable nature facilitates handling under standard laboratory conditions.

Application

1H-Imidazo[4,5-b]pyridine serves as a versatile heterocyclic scaffold in medicinal chemistry, enabling efficient access to biologically active compounds through established functionalization at the 2-, 4-, and 5-positions. Its inherent stability and compatibility with standard coupling reactions facilitate rapid diversification, while its planar structure supports favorable π–π interactions in target binding. This core functions effectively in parallel synthesis campaigns and scale-up processes, offering robust performance in amide bond formation, Suzuki-Miyaura coupling, and electrophilic substitution.
