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

(S)-5-Methylpyrrolidin-2-one is a chiral lactam featuring a stereodefined methyl group at the 5-position, enhancing its utility in asymmetric synthesis. This bench-stable, moisture-tolerant heterocycle serves as a privileged scaffold in medicinal chemistry, integrating readily into bioactive molecules through selective functionalization at the carbonyl and C5 sites.

Application

(S)-5-Methylpyrrolidin-2-one serves as a valuable chiral building block in medicinal chemistry, enabling efficient access to bioactive heterocycles. Its stable pyrrolidinone core exhibits favorable functional group tolerance and facilitates stereoselective transformations. The molecule functions effectively in coupling reactions and acts as a key scaffold for the synthesis of pharmaceutical intermediates under standard bench conditions.
