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

Fmoc-L-allothreonine is a protected amino acid derivative featuring a fluorenylmethoxycarbonyl (Fmoc) group for orthogonal protection in peptide synthesis. This configuration enables efficient N-terminal capping and facilitates purification via standard solid-phase protocols. The allothreonine side chain offers distinct stereochemical properties, enhancing structural diversity in bioactive peptide libraries.

Application

Boc-L-allothreonine, a key chiral building block in peptide synthesis, features a sterically hindered side chain and orthogonal protection for the hydroxyl group. It facilitates efficient solid-phase and solution-phase coupling reactions with excellent functional group tolerance and stability under standard deprotection conditions. The fluorenylmethoxycarbonyl (Fmoc) variant enables sequential addition in automated synthesis while maintaining high diastereoselectivity and purity.
