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+

Description

Fmoc-L-4-acetylphe is a protected amino acid derivative featuring a fluorenylmethoxy carbonyl (Fmoc) group at the N-terminus and an acetyl-modified side chain on the phenylalanine moiety. This combination enables stable incorporation into peptide synthesis workflows, where the Fmoc group facilitates orthogonal deprotection under mild basic conditions. The acetyl substitution enhances metabolic stability in bioactive peptide sequences.

Application

L-4-Acetylphe-(9H-Fluoren-9-yl)methyl ester serves as a stable, bench-ready amino acid building block for peptide synthesis. The fluorenylmethoxycarbonyl (Fmoc) group enables efficient orthogonal protection, while the acetyl side chain provides modulated reactivity and enhanced solubility. This derivative facilitates smooth coupling reactions, minimizes racemization, and simplifies purification—ideal for iterative solid-phase and solution-phase methodologies in medicinal chemistry workflows.
