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.

Description

Fmoc-Dab(Alloc)-OH is a protected diaminobutyric acid derivative featuring a labile Alloc group for selective deprotection. This orthogonal functionality enables precise incorporation into peptide chains during solid-phase synthesis, facilitating the installation of side-chain functional groups at defined stages. The Fmoc moiety ensures efficient N-terminal capping and compatibility with standard coupling protocols.

Application

Fmoc-Dab(Alloc)-OH serves as a key building block in peptide synthesis, enabling the introduction of a side-chain amine with orthogonal protection. The Alloc group allows for selective deprotection under palladium-catalyzed conditions, while the Fmoc moiety ensures efficient stepwise chain elongation. This combination facilitates the construction of complex peptides and functionalized scaffolds with high fidelity and minimal side reactions.
