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-Chlorobenzo[d]thiazole offers a robust heterocyclic scaffold with enhanced electronic properties due to the electron-withdrawing chlorine substituent. This bench-stable compound integrates readily into pharmaceutical and agrochemical intermediates, enabling efficient access to bioactive architectures through C–H functionalization and cross-coupling protocols.

Application

5-Chlorobenzo[d]thiazole serves as a versatile heterocyclic building block in medicinal chemistry and materials science. Its chlorine substituent enables facile palladium-catalyzed cross-coupling reactions, facilitating the construction of biaryl and extended π-conjugated systems. The scaffold exhibits excellent bench stability, compatibility with diverse functional groups, and is readily incorporated into drug-like molecules and advanced organic semiconductors.
