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-Bromo-2-methoxybenzenesulfonamide features a bromine substituent at the para position relative to the sulfonamide group, enhancing electrophilic reactivity. The methoxy group provides electron-donating character and improves solubility in organic solvents. This compound serves as a key intermediate in the synthesis of biologically active sulfonamides and pharmaceuticals requiring halogenated aromatic scaffolds.

Application

5-Bromo-2-methoxybenzenesulfonamide serves as a versatile building block in medicinal chemistry, enabling direct functionalization at the sulfonamide nitrogen and ortho-position to the methoxy group. Its bromine atom facilitates palladium-catalyzed cross-coupling reactions, while the methoxy substituent enhances solubility and modulates electronic properties. The compound exhibits excellent bench stability and compatibility with standard purification techniques, making it ideal for iterative synthesis of heterocyclic scaffolds and API intermediates.
