    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-butyl group and a methyl substituent at the 2-position, conferring enhanced steric bulk and stability. The (R)-configuration at the 2,5-dihydro-1H-pyrrole core enables stereoselective transformations in asymmetric synthesis. Its bench-stable nature and compatibility with standard reaction conditions make it a reliable building block for complex heterocyclic systems.

Application

1-(tert-Butyl) 2-methyl (R)-2,5-dihydro-1H-pyrrole-1,2-dicarboxylate serves as a stable, bench-ready chiral building block for the synthesis of pyrrolidine-based scaffolds. Its tert-butyl ester and methyl substituent provide excellent functional group tolerance and ease of purification, enabling efficient transformations in asymmetric synthesis. The (R)-configured dihydropyrrole core facilitates stereoselective coupling reactions and is well-suited for constructing medicinally relevant heterocyclic frameworks.
