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-D-Dbu(Boc)-OH is a specialized amino acid derivative featuring a D-configured backbone and a bulky, electron-deficient Dbu (1,8-diazabicyclo[5.4.0]undec-7-ene) moiety protected as a Boc group. This combination enables robust coupling in peptide synthesis while minimizing side reactions. The Fmoc group facilitates efficient deprotection under mild conditions, and the sterically hindered Dbu unit enhances solubility and reduces racemization during activation. Ideal for incorporating non-natural residues into complex peptide architectures with improved stability and yield.

Application

Fmoc-D-Dbu(Boc)-OH serves as a versatile, bench-stable building block for peptide and heterocyclic synthesis. The Fmoc group enables efficient N-terminal protection in solid-phase peptide synthesis, while the Boc-protected Dbu moiety provides a rigid, sterically hindered base that facilitates deprotonation in challenging coupling reactions. Its orthogonal functionality supports sequential functionalization strategies, and the stable, crystalline nature simplifies purification and handling.
