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

2-Bromobenzo[d]isothiazol-3(2H)-one 1,1-dioxide is a bench-stable, electron-deficient heterocycle featuring a bromine substituent and sulfone group. This combination imparts enhanced reactivity in cross-coupling processes and improves solubility in polar solvents. The molecule integrates readily into complex scaffolds requiring halogen-directed functionalization.

Application

2-Bromobenzo[d]isothiazol-3(2H)-one 1,1-dioxide serves as a versatile building block for the synthesis of bioactive heterocycles, leveraging its electrophilic bromine and sulfonamide-like functionality. The molecule exhibits bench stability and facilitates palladium-catalyzed cross-coupling reactions, enabling efficient access to substituted benzothiazole scaffolds commonly found in medicinal chemistry. Its functional group tolerance supports downstream derivatization in multi-step syntheses.
