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

(S)-2-((((9H-Fluoren-9-yl)methoxy)carbonyl)(methyl)amino)-5-((tert-butoxycarbonyl)amino)pentanoic acid is a chiral building block featuring a fluorenylmethoxycarbonyl (Fmoc) group for N-terminal protection and a tert-butoxycarbonyl (Boc) group on the side chain. This dual-protected derivative enables selective peptide coupling under mild conditions, offering high stability and compatibility with automated synthesis workflows.

Application

(S)-2-((((9H-Fluoren-9-yl)methoxy)carbonyl)(methyl)amino)-5-((tert-butoxycarbonyl)amino)pentanoic acid serves as a versatile chiral building block for peptide synthesis, enabling efficient Nα-Fmoc and Nε-Boc protection of lysine derivatives. The Fmoc group ensures orthogonal deprotection under mild basic conditions, while the tert-butyl carbamate handles stability during standard coupling protocols. This di-functionalized scaffold facilitates the construction of complex peptide architectures with high fidelity and ease of purification.
