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 (R)-configured fluorenylmethoxycarbonyl-protected amino acid derivative features a sterically hindered trityl group and a labile carbamate linkage, enabling efficient incorporation into peptide chains under mild deprotection conditions. The electron-rich fluoren-9-yl moiety facilitates UV detection during synthesis, while the methylamino functionality supports selective coupling reactions. This robust scaffold delivers high-purity peptides with minimal epimerization.

Application

(R)-2-((((9H-Fluoren-9-yl)methoxy)carbonyl)(methyl)amino)-4-oxo-4-(tritylamino)butanoic acid serves as a robust chiral building block for peptide synthesis, enabling efficient N-terminal protection and side-chain functionalization. The fluorenylmethoxycarbonyl (Fmoc) group ensures orthogonal deprotection under mild basic conditions, while the trityl-protected amine provides steric shielding and enhanced solubility. Its bench-stable nature and compatibility with standard coupling protocols facilitate reliable incorporation into complex peptide scaffolds.
