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
FedEx Limited Quantities Ground	$0.00
Hazmat Ground shipping	$50.00+
Inaccessible (Haz class 6.1 or 9), Domestic	$68.00+
Accessible (Haz class 3, 4, 5 or 8), Domestic	$158.00+
Inaccessible (Haz class 6.1 or 9), International	$108.00+
Accessible (Haz class 3, 4, 5 or 8), International	$238.00+

Description

Boc-Phe(4-Cl)-OH features a para-chlorophenylalanine residue with a tert-butoxycarbonyl protecting group, enabling stable incorporation into peptide chains. The electron-withdrawing chlorine substituent enhances synthetic handling and modulates reactivity during coupling steps. This bench-stable building block supports efficient solid-phase peptide synthesis workflows.

Application

Boc-Phe(4-Cl)-OH serves as a versatile building block in peptide synthesis, enabling efficient incorporation of 4-chlorophenylalanine into target sequences. The Boc group provides robust protection under standard deprotection conditions, while the para-chlorophenyl side chain offers enhanced metabolic stability and modulated electronic properties. This derivative exhibits excellent bench stability, facilitates straightforward purification, and participates reliably in coupling reactions with minimal epimerization.
