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

(R)-2-Amino-4-methoxy-4-oxobutanoic acid features a stereochemically defined chiral center critical for asymmetric synthesis. The molecule integrates a carboxylic acid, amine, and methoxy-substituted ketone within a linear four-carbon framework, enabling direct incorporation into peptide mimetics and bioactive heterocycles under standard conditions. This bench-stable derivative supports efficient derivatization in medicinal chemistry workflows.

Application

(R)-2-Amino-4-methoxy-4-oxobutanoic acid serves as a key chiral building block for synthesizing bioactive heterocycles and peptidomimetics. Its well-defined stereochemistry enables reliable incorporation into complex scaffolds, while the α-amino and β-ketoester functionalities offer orthogonal reactivity for sequential transformations. Bench-stable and amenable to standard purification methods, it facilitates efficient access to medicinally relevant frameworks in both academic and industrial settings.
