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-Bromobenzofuran-3(2H)-one features a brominated benzofuran core with a ketone at the 3-position, delivering enhanced reactivity for transition-metal-catalyzed couplings. This bench-stable heterocycle integrates readily into complex scaffolds, enabling efficient access to bioactive molecules in medicinal chemistry and materials science applications.

Application

5-Bromobenzofuran-3(2H)-one serves as a versatile building block for the synthesis of biologically active heterocycles and pharmaceutical intermediates. Its bromine substituent enables facile palladium-catalyzed cross-coupling reactions, while the lactone functionality offers compatibility with nucleophilic additions and reduction protocols. The compound exhibits excellent bench stability and is readily purified by recrystallization, facilitating its use in multi-step synthetic sequences.
