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+

Description

Boc-L-Alanine benzyl ester serves as a protected amino acid building block for peptide synthesis, featuring a stable tert-butoxycarbonyl group and a benzyl ester that enables selective deprotection. This derivative facilitates efficient coupling reactions under standard conditions while maintaining compatibility with diverse reaction environments.

Application

Boc-L-Alanine benzyl ester serves as a stable, bench-ready amino acid building block for peptide synthesis and medicinal chemistry applications. Its orthogonal protection scheme—tert-butoxycarbonyl (Boc) on the amine and benzyl ester on the carboxylate—enables selective deprotection during multi-step syntheses. The compound exhibits excellent functional group tolerance and facilitates efficient coupling reactions, supporting scalable and reproducible workflows in solid-phase and solution-phase peptide assembly.
