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 side chain with a methyl substituent, enabling selective incorporation into peptide sequences. The C-terminal carboxylic acid group supports efficient coupling reactions, while the Fmoc moiety ensures stable storage and orthogonal deprotection under mild basic conditions.

Application

(S)-2-((((9H-Fluoren-9-yl)methoxy)carbonyl)(methyl)amino)-5-methylhexanoic acid serves as a robust chiral building block for peptide synthesis, enabling efficient incorporation of sterically hindered, branched side chains. The Fmoc-protected amine and pendant methyl group offer enhanced solubility and stability during coupling reactions, while the C5-methyl substituent provides defined stereochemical control. Its bench-stable nature and compatibility with standard SPPS protocols facilitate reliable synthesis of complex peptides and peptidomimetics.
