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

tert-Butyl 3,3-difluoro-4-oxopiperidine-1-carboxylate is a sterically hindered, bench-stable piperidine derivative featuring two fluorine atoms at the C3 position and a ketone at C4. This electron-deficient scaffold integrates readily into complex heterocyclic architectures, enabling efficient access to fluorinated bioactive molecules in medicinal chemistry campaigns.

Application

tert-Butyl 3,3-difluoro-4-oxopiperidine-1-carboxylate serves as a versatile fluorinated piperidine building block, enabling efficient access to difluorinated heterocyclic scaffolds. The 3,3-difluoro substitution enhances metabolic stability and modulates basicity, while the 4-oxo group provides a reactive handle for reductive amination, nucleophilic addition, or cyclization. Bench-stable and readily purified by standard chromatography, it functions effectively in medicinal chemistry campaigns requiring constrained, fluorinated amine motifs.
