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

(R)-1-(((9H-Fluoren-9-yl)methoxy)carbonyl)azetidine-2-carboxylic acid is a chiral, bench-stable building block for peptide synthesis, featuring a sterically constrained azetidine core that enhances conformational rigidity. The fluorenylmethoxycarbonyl (Fmoc) group enables orthogonal protection and efficient coupling under standard conditions. This derivative supports the incorporation of non-canonical amino acids into peptidomimetics with improved metabolic stability and target affinity.

Application

(R)-1-(((9H-Fluoren-9-yl)methoxy)carbonyl)azetidine-2-carboxylic acid serves as a stereochemically defined, bench-stable building block for the synthesis of peptidomimetics and constrained bioactive molecules. The Fmoc group enables efficient orthogonal protection during solid-phase peptide synthesis, while the azetidine core provides conformational rigidity to modulate target binding affinity. Its compatibility with standard coupling conditions and ease of purification make it a practical choice for medicinal chemistry campaigns targeting protease inhibitors and CNS-active compounds.
