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

This fluorenylmethoxycarbonyl-protected amino acid derivative features a chiral benzylic center and a benzyl side chain, enabling selective incorporation into peptide sequences. The Fmoc group ensures orthogonal protection during solid-phase synthesis, while the sterically defined backbone supports high diastereoselectivity in coupling reactions.

Application

(S)-3-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)-2-benzylpropanoic acid serves as a versatile chiral building block for peptide synthesis, enabling efficient incorporation of sterically hindered, β-branched amino acid residues. The Fmoc group provides excellent stability and orthogonal deprotection under mild basic conditions, while the benzyl side chain offers synthetic handle for downstream functionalization. Its bench-stable solid form and compatibility with standard coupling protocols facilitate reliable use in automated and manual SPPS workflows.
