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

3-Bromo-4-fluorobenzene-1-sulfonyl chloride features a sulfonyl chloride group flanked by bromo and fluoro substituents, enabling selective functionalization in synthetic workflows. This electron-deficient aryl scaffold supports efficient coupling reactions under mild conditions, delivering robust intermediates for pharmaceutical and agrochemical development.

Application

3-Bromo-4-fluorobenzene-1-sulfonyl chloride serves as a versatile building block for sulfonamide synthesis, enabling efficient incorporation of a bromo- and fluoro-substituted arylsulfonyl group into target molecules. Its reactivity facilitates coupling with amines under mild conditions, offering excellent functional group tolerance and bench stability. The strategic placement of halogens supports downstream cross-coupling transformations, making it ideal for constructing complex heterocyclic scaffolds and pharmaceutical intermediates in medicinal chemistry workflows.
