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

N-[(9H-Fluoren-9-ylmethoxy)carbonyl]-3-methyl-L-allothreonine is a protected amino acid derivative featuring a fluorenylmethoxycarbonyl (Fmoc) group for orthogonal protection. This sterically hindered side chain enhances stability during peptide synthesis, enabling efficient coupling and minimizing racemization under standard conditions.

Application

N-[(9H-Fluoren-9-ylmethoxy)carbonyl]-3-methyl-L-allothreonine serves as a protected amino acid building block for peptide synthesis, enabling orthogonal incorporation of non-proteinogenic residues. The Fmoc group ensures stable protection under basic conditions and facilitates efficient removal during standard deprotection protocols. The 3-methyl-L-allothreonine side chain provides a sterically constrained, hydroxyl-bearing moiety suitable for introducing conformational rigidity in peptidomimetics and bioactive scaffolds. Offers excellent bench stability and compatibility with diverse coupling reagents.
