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+

Description

H-D-Asp(OMe)-OMe.HCl features a methyl ester-protected aspartic acid scaffold with D-stereochemistry, offering enhanced metabolic stability and resistance to enzymatic degradation. This bench-stable derivative serves as a key building block in peptide synthesis, particularly for sterically constrained sequences requiring controlled reactivity.

Application

H-D-Asp(OMe)-OMe·HCl serves as a stable, bench-ready dipeptide building block featuring a methyl ester-protected aspartic acid residue. Its well-defined stereochemistry and orthogonal functional group tolerance enable reliable incorporation into peptide sequences and heterocyclic scaffolds. The hydrochloride salt enhances solubility and handling, facilitating efficient coupling reactions in solid-phase and solution-phase synthesis.
