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

Dde-Orn(Fmoc)-OH is a protected ornithine derivative featuring a Dde (1,2-dihydro-2,2-dimethyl-2-phenyl-3H-inden-3-on-1-yl) group at the ε-amino position and a Fmoc (fluorenylmethoxycarbonyl) group at the α-amino terminus. This dual protection enables selective deprotection in peptide synthesis, facilitating the incorporation of ornithine residues with orthogonal handling. The compound exhibits stability under standard bench conditions and compatibility with common coupling protocols.

Application

Dde-Orn(Fmoc)-OH serves as a protected ornithine building block for solid-phase peptide synthesis, enabling selective incorporation of ornithine residues with orthogonal deprotection. The Dde (1-(4,4-dimethyl-2,6-dioxocyclohexylidene)ethyl) group allows chemoselective removal under mild hydrazinolysis conditions, preserving Fmoc protection and facilitating sequential assembly in complex peptide architectures. Its stability during standard coupling and activation steps supports reliable yield and purity in multi-step syntheses.
