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+
Accessible (Haz class 3, 4, 5 or 8), International	$238.00+

Description

Fmoc-L-Lys(Dde)-OH serves as a protected lysine derivative for solid-phase peptide synthesis, featuring a Dde (1-(4,4-dimethyl-2,6-dioxocyclohexylidene)ethyl) group that enables selective deprotection under mild conditions. This orthogonal protection strategy facilitates the incorporation of multiple functional side chains in complex peptide architectures. The Fmoc moiety ensures efficient N-terminal capping during chain elongation.

Application

Fmoc-L-Lys(Dde)-OH serves as a key building block in solid-phase peptide synthesis, enabling orthogonal side-chain protection for lysine residues. The Fmoc group facilitates efficient N-terminal deprotection under mild basic conditions, while the Dde (2,4-dimethoxybenzyl) protecting group on the ε-amino function is selectively removable via hydrazinolysis, allowing sequential coupling and modification in complex peptide architectures. Its bench-stable nature and compatibility with standard SPPS workflows make it ideal for synthesizing multi-functionalized peptides and peptidomimetics.
