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)-tert-Butyl 5-oxopyrrolidine-2-carboxylate is a stereochemically defined, bench-stable building block featuring a pyrrolidinone core with a tert-butyl ester handle. This configuration enables direct incorporation into asymmetric synthesis workflows, where the carbonyl group facilitates selective functionalization and the protected amine supports downstream transformations under standard conditions.

Application

(R)-tert-Butyl 5-oxopyrrolidine-2-carboxylate serves as a versatile chiral building block in synthetic organic chemistry, enabling efficient access to pyrrolidine-based scaffolds. Its oxo group at C5 facilitates selective functionalization, while the tert-butyl ester provides excellent bench stability and ease of removal under mild acidic conditions. The compound functions effectively in asymmetric synthesis, supporting diverse transformations including reductive amination, nucleophilic addition, and transition-metal-catalyzed coupling reactions.
