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

This fluorenylmethoxycarbonyl-protected amino acid bears a chiral center at the alpha position, integrating a para-cyanophenyl group for enhanced electronic effects. The (S)-configuration ensures stereochemical fidelity in peptide synthesis, while the fluoren-9-ylmethoxycarbonyl moiety enables efficient orthogonal protection and clean deprotection under mild conditions.

Application

(S)-2-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)-3-(3-cyanophenyl)propanoic acid serves as a valuable chiral building block for peptide synthesis and medicinal chemistry applications. The Fmoc-protected amino acid exhibits excellent bench stability, facilitates straightforward purification via flash chromatography, and enables efficient coupling reactions with broad functional group tolerance. Its 3-cyanophenyl side chain provides a versatile handle for downstream modifications, making it well-suited for constructing bioactive scaffolds in drug discovery programs.
