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 methyl-L-valinate is a sterically hindered amino acid ester featuring a branched aliphatic side chain. This configuration enhances stability and solubility in organic media, enabling efficient incorporation into peptide synthesis workflows. The protected amine facilitates sequential coupling under standard conditions without racemization.

Application

tert-Butyl methyl-L-valinate serves as a stable, bench-ready amino acid derivative enabling efficient peptide coupling and protection of the L-valine side chain. Its tert-butyl ester functionality facilitates orthogonal deprotection under mild acidic conditions, while the methyl group enhances solubility and reduces aggregation during synthesis. This compound functions reliably in standard SPPS workflows and supports high-yielding amide bond formation with minimal racemization.
