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

Alloc-Val-Ala-OH is a protected tripeptide building block featuring an Alloc (allyloxycarbonyl) group at the N-terminus and a C-terminal hydroxyl. This configuration enables orthogonal deprotection strategies in peptide synthesis, offering enhanced control during sequential coupling steps. The Val-Ala sequence provides a stable, sterically defined scaffold suitable for solid-phase and solution-phase applications.

Application

Alloc-Val-Ala-OH serves as a protected dipeptide building block for peptide synthesis, enabling efficient incorporation of valine and alanine residues with orthogonal protection. The allyloxycarbonyl (Alloc) group provides stable, acid-labile N-terminal protection compatible with standard coupling protocols and selective removal via palladium-catalyzed deprotection. Its bench-stable form facilitates handling, purification, and use in both solution-phase and solid-phase workflows.
