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

Benzo[d]thiazole-6-sulfonyl chloride delivers a reactive sulfonyl chloride handle positioned ortho to the heterocyclic core, enabling direct conjugation with nucleophiles under mild conditions. This electron-deficient scaffold integrates readily into bioactive architectures, offering enhanced metabolic stability and solubility in polar media.

Application

Benzo[d]thiazole-6-sulfonyl chloride serves as a versatile building block for constructing sulfonamide-containing heterocycles, enabling efficient incorporation into pharmaceutical scaffolds. Its reactive sulfonyl chloride group facilitates direct amidation and nucleophilic substitution under mild conditions, offering high functional group tolerance and bench stability. Widely employed in medicinal chemistry, it functions as a key intermediate in the synthesis of kinase inhibitors and other bioactive compounds, with predictable reactivity profiles suitable for both small-scale exploration and process-scale applications.
