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 amino acid derivative features a chiral (R)-configuration at the alpha carbon, enabling stereoselective peptide synthesis. The C-terminal carboxylic acid group and N-terminal Fmoc moiety facilitate efficient coupling reactions, while the tert-butoxycarbonyl-methylamino side chain provides a stable, orthogonal protecting group for selective deprotection. Designed for solid-phase peptide synthesis, this reagent ensures high yield and purity in complex sequence assembly.

Application

(R)-2-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)-6-((tert-butoxycarbonyl)(methyl)amino)hexanoic acid serves as a versatile chiral building block for peptide synthesis, enabling efficient N-terminal protection and side-chain modulation. The Fmoc group ensures orthogonal deprotection under mild basic conditions, while the Boc-methyl amino functionality provides a stable, selectively removable amine handle. Its bench-stable, crystalline nature facilitates straightforward purification and compatibility with standard coupling protocols in solid-phase and solution-phase workflows.
