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

This chiral pyrrolidine derivative features a tert-butoxycarbonyl-protected amine and a phenyl-substituted C4 position, enabling direct incorporation into peptide backbones. The stereochemistry at the 2R,4R centers ensures predictable conformational behavior in foldamers and constrained peptides. Bench-stable and moisture-tolerant, it streamlines synthesis of non-natural amino acid building blocks for medicinal chemistry campaigns.

Application

(2R,4R)-1-(tert-butoxycarbonyl)-4-phenylpyrrolidine-2-carboxylic acid serves as a stereochemically defined building block for the synthesis of bioactive pyrrolidine-containing scaffolds. The Boc group enables straightforward deprotection under mild acidic conditions, while the phenyl and carboxylic acid functionalities offer versatile handles for further functionalization. Its stability and compatibility with standard coupling protocols make it ideal for peptide and medicinal chemistry applications requiring controlled stereochemistry and modular side-chain elaboration.
