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

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+

Description

This fluorenylmethoxycarbonyl-protected amino acid derivative features a chiral (3R) configuration and a reactive ketone moiety, enabling site-specific conjugation in peptide synthesis. The C-terminal carbonyl group facilitates efficient coupling reactions under standard conditions, while the fluorenylmethoxycarbonyl group provides robust protection and orthogonal deprotection compatibility. This structure supports the incorporation of biologically active motifs into complex peptides with high fidelity.

Application

(3R)-4-Amino-3-[[(9H-fluoren-9-ylmethoxy)carbonyl]amino]-4-oxobutanoic acid serves as a key chiral building block for the synthesis of peptidomimetics and β-amino acid derivatives. The Fmoc group provides orthogonal protection for the amine, enabling selective deprotection during solid-phase peptide synthesis. Its α,β-unsaturated carbonyl system facilitates conjugate addition reactions and participates in standard coupling protocols with high functional group tolerance. Bench-stable and readily purified by flash chromatography, it functions effectively in multi-step synthetic sequences requiring precise stereocontrol.
