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

Hazmat Ground shipping	$50.00+
Inaccessible (Haz class 6.1 or 9), Domestic	$68.00+

Description

H-Asp-OMe features a methyl ester-protected aspartic acid residue, offering enhanced solubility and stability in aqueous and organic solvents. This derivative simplifies peptide synthesis workflows by enabling direct incorporation without additional protection steps, particularly valuable in the construction of biologically active sequences requiring C-terminal modifications.

Application

H-Asp-OMe serves as a versatile building block in peptide synthesis, offering a readily accessible C-terminal methyl ester derivative of aspartic acid. Its well-established stability under standard coupling conditions facilitates efficient incorporation into peptide sequences, while the carboxylic acid functionality enables selective derivatization. The molecule exhibits favorable solubility and ease of purification, supporting robust performance in both solution-phase and solid-phase workflows.
