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+

Description

Boc-N-methyl-L-isoleucine offers a sterically hindered, bench-stable side chain ideal for peptide synthesis. The N-methyl group reduces amide hydrogen bonding, enhancing membrane permeability in bioactive sequences. This protected amino acid integrates efficiently into complex peptides under standard coupling conditions.

Application

Boc-N-methyl-L-isoleucine serves as a valuable chiral building block for peptide synthesis, offering enhanced stability and solubility in organic media. The Boc group provides reliable protection of the α-amino function, while the N-methyl substitution reduces amide hydrogen bonding and improves membrane permeability in peptidomimetic applications. Its isoleucine side chain supports stereocontrolled assembly of complex scaffolds, facilitating efficient coupling reactions with minimal racemization.
