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

(S)-Fmoc-2-Amino-4,4-Difluoropentanoic Acid features a sterically hindered difluoromethyl group that enhances metabolic stability in peptide synthesis. The Fmoc protecting group enables efficient N-terminal coupling under standard conditions, while the chiral amino acid backbone supports high diastereoselectivity in chain elongation. This derivative serves as a key building block for fluorinated peptidomimetics and bioactive oligomers.

Application

(S)-Fmoc-2-Amino-4,4-difluoropentanoic acid serves as a valuable chiral building block for peptide synthesis and medicinal chemistry. The Fmoc group enables efficient solid-phase peptide coupling, while the 4,4-difluoropentanoic acid moiety imparts enhanced metabolic stability and modulates physicochemical properties. Its bench-stable nature and compatibility with standard coupling conditions facilitate reliable incorporation into complex scaffolds.
