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

5-Chlorothiazolo[5,4-b]pyridine is a heterocyclic scaffold featuring a fused thiazole-pyridine core with a chlorine substituent at the 5-position. This electron-deficient system enables direct functionalization in cross-coupling reactions and serves as a privileged motif in medicinal chemistry for targeted kinase inhibition and antiviral agent development.

Application

5-Chlorothiazolo[5,4-b]pyridine serves as a versatile heterocyclic building block for medicinal chemistry and materials science applications. Its reactive chlorine atom enables efficient Suzuki-Miyaura, Buchwald-Hartwig, and nucleophilic substitution reactions, facilitating the construction of biologically active scaffolds. The fused thiazole-pyridine core provides enhanced metabolic stability and tunable electronic properties, making it valuable in the development of kinase inhibitors and other targeted therapeutics. Bench-stable and compatible with standard synthetic protocols, it functions as a reliable intermediate in complex molecule assembly.
