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

4-Bromo-2,6-dimethoxybenzenesulfonyl chloride features a sulfonyl chloride group flanked by bromo and dimethoxy substituents, enabling selective functionalization in synthetic routes. This electron-deficient arylsulfonyl chloride offers enhanced reactivity and stability under standard conditions, facilitating efficient incorporation into complex molecular architectures.

Application

4-Bromo-2,6-dimethoxybenzenesulfonyl chloride serves as a versatile sulfonylating agent for the efficient introduction of a sterically hindered, electron-rich sulfonyl group. Its bromo and methoxy substituents enhance solubility and facilitate downstream functionalization via cross-coupling. The reagent exhibits excellent bench stability and enables clean derivatization of amines and alcohols under mild conditions, making it ideal for constructing sulfonamide and sulfonate building blocks in medicinal chemistry and process development workflows.
