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+

Description

Benzyl N6-(t-Boc)-L-lysinate serves as a protected lysine derivative featuring a benzyl ester and tert-butoxycarbonyl group, enabling orthogonal handling in peptide synthesis. This stable, moisture-tolerant reagent integrates seamlessly into solid-phase workflows, delivering efficient coupling with minimal racemization.

Application

Benzyl N⁶-(t-Boc)-L-lysinate serves as a versatile amino acid building block for peptide synthesis, offering orthogonal protection of the ε-amino group via the t-Boc moiety while preserving the side-chain functionality. The benzyl ester facilitates efficient deprotection under mild hydrogenolysis conditions, enabling straightforward access to free carboxylic acid derivatives. This compound exhibits excellent bench stability and compatibility with standard coupling reagents, making it ideal for iterative solid-phase and solution-phase peptide assembly workflows.
