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

(S)-2-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)-3-(o-tolyl)propanoic acid is a chiral building block featuring a fluorenylmethoxycarbonyl (Fmoc) protected amino group and a sterically hindered o-tolyl side chain. This configuration enables efficient incorporation into peptide synthesis workflows, where the Fmoc group facilitates orthogonal deprotection under mild basic conditions. The o-tolyl moiety contributes rigidity and enhanced solubility in organic solvents, improving handling during solid-phase peptide assembly.

Application

(S)-2-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)-3-(o-tolyl)propanoic acid serves as a robust chiral building block for peptide synthesis, offering high diastereoselectivity in amide bond formation. The Fmoc group enables convenient orthogonal protection and facile removal under mild basic conditions, while the o-tolyl side chain provides steric and electronic stability. Its bench-stable nature and compatibility with standard coupling protocols make it ideal for iterative solid-phase and solution-phase peptide assembly.
