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+

Description

This fluoren-9-ylmethoxycarbonyl (Fmoc)-protected amino acid derivative features a chiral (R)-configuration at the α-carbon, enabling stereoselective peptide synthesis. The bulky fluoren-9-ylmethyl group enhances solubility and stability during solid-phase assembly, while the pendant methyl-substituted aliphatic chain provides steric differentiation. This combination supports efficient coupling and minimizes racemization under standard conditions.

Application

(R)-2-(((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)methyl)-4-methylpentanoic acid serves as a robust chiral building block for peptide synthesis, offering high stereoselectivity and bench stability. The Fmoc group enables efficient N-terminal protection with orthogonal deprotection under mild basic conditions, while the aliphatic side chain supports diverse functionalization. Its compatibility with standard coupling protocols and ease of purification make it ideal for solid-phase and solution-phase peptide assembly.
