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-5-ethoxyfuran-2(5H)-one features a brominated furanone scaffold with enhanced solubility and stability under standard conditions. The ethoxy substituent improves reactivity in transition-metal-catalyzed couplings, while the electrophilic carbonyl facilitates nucleophilic addition. This compound serves as a key intermediate in heterocyclic synthesis.

Application

4-Bromo-5-ethoxyfuran-2(5H)-one serves as a versatile building block in heterocyclic synthesis, enabling efficient access to substituted furan derivatives via palladium-catalyzed cross-coupling reactions. The bromine and ethoxy groups provide orthogonal functional handles for sequential transformations, while the α,β-unsaturated γ-lactone framework exhibits bench stability and compatibility with diverse reaction conditions. Its predictable reactivity facilitates integration into complex molecular architectures relevant to medicinal chemistry and agrochemical research.
