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.

Description

This chiral building block features a fluorenylmethoxycarbonyl (Fmoc)-protected amine and a cyclopentyl-substituted acetic acid moiety, enabling direct incorporation into peptide chains. The stereochemistry at the α-carbon ensures high diastereoselectivity in coupling reactions, while the Fmoc group provides orthogonal protection for amine-directed synthesis.

Application

(S)-2-((((9H-Fluoren-9-yl)methoxy)carbonyl)(methyl)amino)-2-cyclopentylacetic acid serves as a robust chiral building block for peptide synthesis, enabling efficient incorporation of sterically hindered, non-proteinogenic amino acid motifs. The Fmoc group provides excellent stability and orthogonal deprotection, while the methylamino and cyclopentyl functionalities offer defined stereochemical control and enhanced lipophilicity—ideal for medicinal chemistry campaigns requiring tailored scaffold diversity.
