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

(S)-2-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)-3-(oxazol-5-yl)propanoic acid features a chiral center flanked by a fluorenylmethoxycarbonyl (Fmoc) protecting group and a sterically constrained oxazol-5-yl side chain. This combination enables efficient incorporation into peptide synthesis workflows, offering enhanced solubility and stability under standard coupling conditions.

Application

(S)-2-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)-3-(oxazol-5-yl)propanoic acid serves as a valuable chiral building block in peptide synthesis, enabling efficient incorporation of oxazol-5-yl functionality at the C-terminal position. The Fmoc group provides excellent stability and ease of removal under mild basic conditions, while the oxazol-5-yl side chain offers a robust heterocyclic moiety with proven utility in medicinal chemistry scaffolds. Its compatibility with standard coupling protocols and straightforward purification make it well-suited for both academic and industrial peptide workflows.
