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

Methyl 4-Bromo-2-(methylsulfonyl)benzoate features a bromine atom at the para position relative to the ester group and a methylsulfonyl substituent at the ortho position, creating a uniquely activated aromatic system. This combination enables efficient palladium-catalyzed cross-coupling reactions and facilitates direct functionalization in synthetic sequences. The molecule exhibits excellent stability under standard bench conditions and integrates readily into complex molecular architectures requiring orthogonal reactivity.

Application

Methyl 4-Bromo-2-(methylsulfonyl)benzoate serves as a versatile building block in cross-coupling chemistry, enabling palladium-catalyzed reactions such as Suzuki-Miyaura and Stille couplings. The bromo group facilitates efficient C–C bond formation, while the methylsulfonyl moiety enhances solubility and provides orthogonal reactivity. Its bench-stable nature and compatibility with diverse functional groups make it ideal for constructing complex aromatic scaffolds in medicinal chemistry and materials science applications.
