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
Excepted Quantity	$0.00

Description

Fmoc-Phe(2-Cl)-OH is a fluorophore-tagged amino acid derivative featuring a 2-chlorophenyl side chain, enabling enhanced solubility and stability in solid-phase peptide synthesis. This ortho-chlorinated phenyl group improves electronic coupling and facilitates downstream conjugation. The Fmoc protecting group ensures efficient N-terminal deprotection under mild basic conditions.

Application

Fmoc-Phe(2-Cl)-OH serves as a valuable building block in peptide synthesis, offering enhanced hydrophobicity and steric bulk via the ortho-chlorophenyl side chain. The Fmoc group enables efficient base-labile N-terminal protection, facilitating standard SPPS protocols. This derivative exhibits excellent bench stability, straightforward purification, and compatibility with diverse coupling reagents, making it well-suited for constructing bioactive peptides and heterocyclic scaffolds requiring halogenated aromatic functionality.
