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)-Di-tert-butyl 5-oxopyrrolidine-1,2-dicarboxylate is a sterically hindered chiral synthon featuring a protected pyrrolidine core with a ketone at the C5 position. This configuration enables selective functionalization in asymmetric synthesis, particularly in the construction of nitrogen-containing heterocycles and peptidomimetics. The tert-butyl groups confer enhanced stability and solubility under standard bench conditions.

Application

(R)-Di-tert-butyl 5-oxopyrrolidine-1,2-dicarboxylate serves as a versatile chiral synthon for the construction of pyrrolidine-based scaffolds in medicinal chemistry. Its sterically protected diester functionality enables selective transformations, including reduction to the corresponding amine derivative and subsequent coupling reactions. The molecule exhibits excellent bench stability and facilitates efficient purification, making it well-suited for multi-step synthesis and scale-up applications.
