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+

Description

Fmoc-D-Phe(4-Me)-OH features a fluorophore-masked D-phenylalanine derivative with a para-methyl substituent, enabling efficient incorporation into peptide chains. The electron-donating methyl group enhances stability and modulates backbone conformation during solid-phase synthesis. This bench-stable building block facilitates the installation of D-configured aromatic residues in bioactive peptide sequences.

Application

Fmoc-D-Phe(4-Me)-OH serves as a key building block in peptide synthesis, enabling the incorporation of D-phenylalanine with a para-methyl substituent. The Fmoc group provides orthogonal protection for amine functionality, facilitating efficient stepwise chain elongation. The 4-methylphenyl side chain enhances hydrophobicity and steric bulk, offering favorable properties for peptide stability and receptor interaction. This derivative exhibits excellent bench stability, clean coupling efficiency, and compatibility with standard purification methods, making it ideal for medicinal chemistry and peptide library development.
