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.

Description

L-Asparagine is a polar, neutral amino acid featuring a carboxamide side chain that enhances solubility and hydrogen-bonding capacity. This structural motif supports its role in protein folding stability and serves as a key nitrogen donor in biosynthetic pathways. The molecule exhibits bench-stable behavior under standard conditions, enabling reliable use in cell culture media and peptide synthesis workflows.

Application

L-Asparagine serves as a key building block in peptide synthesis and protein engineering, offering reliable side-chain amide functionality for site-specific conjugation and structural stabilization. Its bench-stable nature and compatibility with standard coupling protocols facilitate efficient incorporation into synthetic peptides and bioconjugates. Functions as a critical residue in the construction of biologically active scaffolds and glycoprotein analogs.
