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

Ethyl 4,4-difluoro-3-oxobutanoate features a sterically hindered β-keto ester scaffold with two fluorine atoms at the α-position, enhancing electrophilicity and metabolic stability. This bench-stable reagent integrates readily into Michael additions and condensation cascades, enabling efficient access to fluorinated heterocycles and complex carbonyl architectures under mild conditions.

Application

Ethyl 4,4-difluoro-3-oxobutanoate serves as a versatile building block in synthetic organic chemistry, enabling the construction of fluorinated heterocycles and bioactive scaffolds. Its α,α-difluoroketone functionality facilitates enolization and subsequent nucleophilic additions, while the ester group supports transformations such as reductions, hydrolyses, and coupling reactions. The molecule exhibits good bench stability and ease of purification, making it well-suited for iterative synthesis workflows in medicinal chemistry and process development.
