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

Fmoc-(S)-3-Amino-4-(2-chlorophenyl)-butyric acid is a chiral building block featuring a fluorinated benzyl protecting group and a chlorinated aryl moiety. This derivative enables direct incorporation into peptide sequences via standard coupling protocols, offering enhanced solubility and stability during solid-phase synthesis. The para-chloro substituent provides tunable electronic properties for downstream functionalization.

Application

Fmoc-(S)-3-Amino-4-(2-chlorophenyl)-butyric acid serves as a valuable building block for the synthesis of biologically active peptides and peptidomimetics. The Fmoc group enables efficient solid-phase peptide synthesis, while the 2-chlorophenyl moiety imparts structural rigidity and modulates electronic properties. This amino acid derivative exhibits excellent bench stability, tolerates standard coupling conditions, and facilitates purification via chromatography, making it ideal for medicinal chemistry campaigns targeting kinase inhibitors and other bioactive scaffolds.
