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-(4-Bromophenyl)-3-((tert-butoxycarbonyl)amino)propanoic acid features a chiral benzylic center bearing a brominated aryl group and a protected amino functionality. This configuration enables selective incorporation into peptide architectures, where the tert-butyl carbamate moiety provides stability and orthogonal deprotection. The electron-withdrawing bromine enhances reactivity in coupling processes, while the bench-stable, moisture-tolerant structure supports reliable handling under standard synthetic conditions.

Application

(R)-3-(4-Bromophenyl)-3-((tert-butoxycarbonyl)amino)propanoic acid serves as a key chiral building block for the synthesis of biologically active compounds, particularly in medicinal chemistry and peptide-based drug discovery. The molecule features a stable (R)-configured stereocenter, a pendant 4-bromophenyl group enabling further cross-coupling transformations, and a Boc-protected amine that facilitates sequential functionalization. Its bench-stable nature and compatibility with standard coupling and deprotection protocols make it ideal for modular scaffold assembly.
