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+

Description

This fluorenylmethoxycarbonyl-protected cyclobutane derivative serves as a robust, bench-stable amino acid surrogate for peptide synthesis. The rigid cyclobutane scaffold imparts conformational constraint, while the Fmoc group enables orthogonal deprotection. Ideal for incorporating sterically defined residues into bioactive peptides and cyclic architectures.

Application

1-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)cyclobutane-1-carboxylic acid serves as a robust, bench-stable amino acid derivative for peptide synthesis. The Fmoc group enables efficient N-terminal protection with orthogonal deprotection under mild basic conditions. The cyclobutane core provides conformational rigidity, facilitating the incorporation of constrained motifs in bioactive peptide sequences. Compatible with standard coupling protocols and offering clean purification via crystallization or chromatography, this building block supports scalable synthesis of cyclic peptides and peptidomimetics.
