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

1-Bromo-4-(ethylsulfonyl)benzene features a bromine substituent flanked by an electron-withdrawing ethylsulfonyl group, enabling selective cross-coupling reactions. This aryl halide exhibits enhanced stability and solubility in polar organic media, facilitating efficient transformations under standard catalytic conditions.

Application

1-Bromo-4-(ethylsulfonyl)benzene serves as a versatile building block in cross-coupling reactions, enabling efficient construction of biaryl and heteroaryl architectures. The ethylsulfonyl group provides strong electron-withdrawing character and excellent stability under standard reaction conditions. Its bromide functionality facilitates reliable Suzuki, Stille, and Negishi couplings, while the sulfonamide moiety offers orthogonal reactivity for downstream functionalization. Ideal for medicinal chemistry and materials synthesis, it combines bench stability with predictable transformation profiles in multi-step syntheses.
