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.

Type	HazMat Fee
Excepted Quantity	$0.00
FedEx Limited Quantities Ground	$0.00
Hazmat Ground shipping	$50.00+
Inaccessible (Haz class 6.1 or 9), Domestic	$68.00+
Accessible (Haz class 3, 4, 5 or 8), Domestic	$158.00+
Inaccessible (Haz class 6.1 or 9), International	$108.00+

Description

Alloc-Val-Ala-pAB features a photolabile p-azidobenzyl protecting group enabling precise spatiotemporal control in peptide synthesis. This tripeptide integrates cleanly into solid-phase workflows, offering stable storage and efficient release upon UV irradiation. The Alloc moiety ensures orthogonal deprotection, while the C-terminal pAB facilitates downstream conjugation.

Application

Alloc-Val-Ala-pAB serves as a robust peptide building block for solid-phase synthesis, enabling efficient N-terminal protection and orthogonal deprotection under mild conditions. The Alloc group provides excellent stability during standard coupling steps and can be selectively removed with palladium(0) catalysts, facilitating clean chain elongation. The pAB (para-aminobenzyl) moiety enables convenient purification via ion-exchange chromatography and facilitates downstream conjugation. This tripeptide fragment is well-suited for the construction of complex peptide scaffolds in medicinal chemistry and protein engineering workflows.
