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.

Description

(R)-3-((tert-Butoxycarbonyl)amino)-2-phenylpropanoic acid is a chiral building block featuring a protected α-amino acid scaffold with a phenyl group at the β-position. This bench-stable derivative enables straightforward deprotection and incorporation into peptide sequences, facilitating synthesis of enantiopure pharmaceutical intermediates.

Application

(R)-3-((tert-Butoxycarbonyl)amino)-2-phenylpropanoic acid serves as a versatile chiral building block in peptide synthesis and medicinal chemistry, enabling efficient access to β-amino acid scaffolds. The tert-butyl carbamate group provides excellent stability and orthogonal deprotection under mild acidic conditions, while the phenyl-substituted α-carbon supports stereoselective transformations. Its bench-stable nature and compatibility with standard coupling protocols facilitate reliable incorporation into complex molecular architectures.
