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 fluoren-9-ylmethoxycarbonyl-protected chiral amino acid features a cyclopropyl group at the α-position, enhancing steric definition and metabolic stability. The (R)-configuration ensures enantioselective incorporation in peptide synthesis workflows. Designed for efficient coupling under standard conditions, this building block delivers high diastereoselectivity and compatibility with diverse reaction environments.

Application

(R)-2-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)-2-cyclopropylacetic acid serves as a valuable chiral building block in peptide synthesis, enabling the introduction of sterically hindered, cyclopropyl-containing amino acid residues. The Fmoc group provides orthogonal protection for primary amines, offering excellent stability under basic conditions and facilitating straightforward deprotection. Its well-defined stereochemistry and compatibility with standard coupling protocols make it ideal for solid-phase and solution-phase peptide assembly.
