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

4-Bromo-2-chlorobenzo[d]thiazole features a fused heterocyclic core with strategically positioned halogens, enabling direct functionalization in cross-coupling reactions. The electron-deficient thiazole ring facilitates nucleophilic substitution, while the bromo and chloro substituents offer orthogonal reactivity for sequential derivatization. This compound serves as a robust scaffold in medicinal chemistry and materials science.

Application

4-Bromo-2-chlorobenzo[d]thiazole serves as a versatile building block in medicinal chemistry and materials science, enabling efficient construction of biologically active heterocycles. Its dual halogenation pattern facilitates palladium-catalyzed cross-coupling reactions with high chemoselectivity and functional group tolerance. The molecule exhibits excellent bench stability and ease of purification, making it well-suited for iterative synthesis workflows and scale-up applications in API development.
