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

Tert-butyl L-valinate is a bench-stable, moisture-tolerant amino acid derivative featuring a bulky tert-butyl ester group that enhances solubility in organic solvents. This protected L-valine variant facilitates efficient peptide coupling reactions and serves as a key building block in synthetic peptide workflows.

Application

Tert-butyl L-valinate serves as a robust, bench-stable amino acid derivative widely used in peptide synthesis. Its tert-butyl ester group provides excellent compatibility with standard coupling protocols and facilitates straightforward deprotection under mild acidic conditions. The L-valine backbone offers defined stereochemistry and functional group tolerance, enabling efficient incorporation into complex peptide sequences and heterocyclic scaffolds.
