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+
Accessible (Haz class 3, 4, 5 or 8), Domestic	$158.00+

Description

2-Bromo-5-chlorothiazolo[4,5-b]pyridine features a fused thiazolopyridine core with orthogonal halogen substituents enabling selective cross-coupling. This electron-deficient heterocycle integrates readily into pharmaceutical scaffolds and serves as a key intermediate in the synthesis of bioactive molecules.

Application

2-Bromo-5-chlorothiazolo[4,5-b]pyridine serves as a versatile building block for heterocyclic synthesis, enabling palladium-catalyzed cross-coupling reactions due to its orthogonal halogen reactivity. The bromo and chloro substituents facilitate sequential functionalization, offering predictable regioselectivity in C–C and C–heteroatom bond formation. Its bench-stable crystalline form simplifies handling and purification, making it well-suited for medicinal chemistry campaigns and API intermediate development.
