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+
Accessible (Haz class 3, 4, 5 or 8), Domestic	$158.00+

Description

(S)-Ethyl 4-amino-2-((tert-butoxycarbonyl)amino)-4-oxobutanoate features a chiral center and a protected α-amino carbonyl motif, enabling direct incorporation into peptide backbones. The tert-butyl carbamate group ensures stability during synthetic manipulations, while the ethyl ester facilitates selective derivatization. This building block supports efficient access to non-proteinogenic amino acid scaffolds under standard conditions.

Application

(S)-Ethyl 4-amino-2-((tert-butoxycarbonyl)amino)-4-oxobutanoate serves as a key chiral building block for the synthesis of β-lactam antibiotics and peptidomimetics. Its protected amine and ester functionalities enable orthogonal transformations, while the α-amino ketone moiety facilitates stereoselective cyclizations. The tert-butyl carbamate group provides stability and ease of removal under mild acidic conditions, enhancing its utility in multi-step synthetic sequences.
