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 valinate is a bench-stable, moisture-tolerant ester featuring a sterically hindered tert-butyl group that enhances kinetic stability. This robust protecting group integrates seamlessly into peptide synthesis workflows, enabling efficient N-α protection of amino acids with minimal side reactions. The para-substituted aromatic scaffold ensures compatibility across diverse coupling conditions and simplifies purification.

Application

Tert-butyl valinate serves as a stable, bench-friendly amino acid derivative enabling efficient peptide coupling and amide bond formation. Its tert-butyl ester group provides excellent functional group tolerance and simplifies purification via standard acidolysis, facilitating the synthesis of complex peptides and pharmaceutical intermediates under mild conditions.
