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.

Type	HazMat Fee

Description

Fmoc-(R)-3-Amino-3-(3-chlorophenyl)-propionic acid is a bench-stable, moisture-tolerant building block for peptide synthesis. This chiral amino acid features a para-chlorinated aromatic side chain that enhances lipophilicity and metabolic stability. The Fmoc group enables efficient N-terminal protection during solid-phase peptide coupling workflows.

Application

Fmoc-(R)-3-Amino-3-(3-chlorophenyl)-propionic acid serves as a valuable building block for the synthesis of peptidomimetics and bioactive scaffolds. Its Fmoc-protected amine enables efficient solid-phase peptide synthesis, while the pendant 3-chlorophenyl group provides steric and electronic modulation. The molecule exhibits excellent bench stability, facilitates straightforward purification, and tolerates a broad range of reaction conditions, making it ideal for iterative coupling and heterocycle formation in medicinal chemistry workflows.
