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-Arginine is a semi-essential amino acid featuring a guanidino group that confers strong basicity and hydrogen-bonding capacity. This polar side chain enhances solubility in aqueous environments and supports roles in nitric oxide synthesis, urea cycle metabolism, and protein stability. Its presence in enzymatic active sites underscores functional relevance in catalytic processes.

Application

L-Arginine serves as a vital building block in peptide synthesis and metabolic pathway studies, functioning as a key precursor for nitric oxide and urea cycle intermediates. Its guanidino side chain enables robust hydrogen bonding and charge stabilization in biological systems, while its bench-stable crystalline form facilitates handling and purification. Widely used in biochemical assays and cell culture media, L-Arginine supports endothelial function and protein engineering workflows with consistent performance across standard synthetic and biological applications.
