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

Description

(R)-3-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)-5-methylhexanoic acid is a chiral amino acid derivative featuring a fluorenylmethoxycarbonyl (Fmoc) protecting group. This configuration ensures high enantioselectivity in peptide synthesis, enabling efficient incorporation into oligopeptides under standard coupling conditions. The molecule combines excellent solubility with bench-stable handling characteristics, streamlining purification and automation workflows in solid-phase peptide synthesis.

Application

(R)-3-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)-5-methylhexanoic acid serves as a robust chiral building block for peptide synthesis, enabling efficient N-terminal protection with orthogonal deprotection under mild conditions. The Fmoc group ensures high stability during storage and handling, while the branched aliphatic side chain provides steric differentiation useful in conformationally constrained peptide design. Facilitates straightforward purification and compatibility with standard solid-phase protocols.
