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 activated ester features a pyrrolidinone ring that enhances hydrolytic stability while enabling efficient coupling to amines under mild conditions. The cyanoacetate moiety provides a reactive handle for conjugation, delivering high yields in amide bond formation without racemization. Ideal for peptide synthesis and bioconjugation workflows requiring precise control and clean reaction profiles.

Application

2,5-Dioxopyrrolidin-1-yl 2-cyanoacetate serves as a highly effective activated ester for amide bond formation, enabling efficient coupling of carboxylic acids with amines under mild conditions. Its stability in storage and ease of purification make it ideal for peptide synthesis and medicinal chemistry applications. The cyano group provides additional reactivity for downstream transformations, such as nucleophilic additions or heterocycle formation.
