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)-Methyl 3-amino-2-((tert-butoxycarbonyl)amino)propanoate hydrochloride features a chiral α-amino acid scaffold with orthogonal protection: the amine is masked as a tert-butoxycarbonyl (Boc) group, while the carboxylic acid is esterified. This configuration enables selective deprotection and coupling in peptide synthesis workflows. The hydrochloride salt enhances solubility and handling stability under standard bench conditions.

Application

(S)-Methyl 3-amino-2-((tert-butoxycarbonyl)amino)propanoate hydrochloride serves as a key chiral building block in peptide synthesis and medicinal chemistry. The protected amine and carboxylate functionalities enable orthogonal transformations, while the (S)-configuration ensures stereochemical fidelity in target molecules. Bench-stable and readily purified by crystallization, it facilitates efficient coupling reactions and downstream derivatization in multi-step syntheses.
