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

3-Bromothieno[2,3-b]pyridine is a heteroaromatic building block featuring a brominated thienopyridine core. This scaffold integrates a reactive halogen site with extended π-conjugation, enabling direct functionalization in cross-coupling reactions. The molecule exhibits enhanced stability and solubility in organic media, facilitating its use in pharmaceutical synthesis and materials chemistry.

Application

3-Bromothieno[2,3-b]pyridine serves as a versatile building block in heterocyclic synthesis, enabling palladium-catalyzed cross-coupling reactions for the construction of biologically relevant scaffolds. Its bromine substituent offers high reactivity in standard Suzuki, Stille, and Negishi transformations, while the fused thienopyridine core provides enhanced planarity and electron-rich character. The compound exhibits excellent bench stability and facilitates straightforward purification, making it well-suited for iterative medicinal chemistry campaigns and process-scale applications.
