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-Bromobenzo[d]isothiazole features a bromine substituent at the 5-position of a fused benzo[d]isothiazole core, delivering enhanced reactivity for cross-coupling and functionalization. This electron-deficient heterocycle integrates readily into pharmaceutical intermediates and materials precursors, offering improved stability and selectivity under standard conditions.

Application

5-Bromobenzo[d]isothiazole serves as a versatile building block for constructing biologically relevant heterocyclic scaffolds. The bromine substituent enables palladium-catalyzed cross-coupling reactions, facilitating the assembly of complex aryl architectures. Its stability under standard reaction conditions and compatibility with common functional groups make it a practical choice for medicinal chemistry and process development workflows.
