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 hydroxyproline derivative features a stereodefined (S)-configuration and a bench-stable tert-butyl ester, enabling direct incorporation into peptide chains under standard coupling conditions. The orthogonal protecting groups facilitate selective deprotection during synthetic workflows.

Application

tert-Butyl (S)-3-((((9H-fluoren-9-yl)methoxy)carbonyl)amino)-4-hydroxybutanoate serves as a protected hydroxy amino acid building block for peptide synthesis, enabling the incorporation of (S)-4-hydroxyproline motifs. The Fmoc group provides orthogonal protection for the amine, while the tert-butyl ester allows selective deprotection under mild acidic conditions. Its bench-stable nature and compatibility with standard coupling protocols facilitate efficient solid-phase and solution-phase peptide assembly.
