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

1-(Chloroacetyl)pyrrolidine is a reactive acylating agent featuring a chloroacetyl group tethered to a pyrrolidine ring. This configuration enables selective functionalization of nucleophiles, particularly amines and thiols, under mild conditions. The molecule combines high reactivity with bench-stable handling, making it valuable for bioconjugation and synthetic intermediate applications.

Application

1-(Chloroacetyl)pyrrolidine serves as a versatile acylating agent in synthetic organic chemistry, enabling efficient introduction of chloroacetyl groups into nucleophilic substrates. Its bench-stable nature and compatibility with diverse functional groups facilitate straightforward incorporation into complex molecules. The molecule functions effectively in the construction of heterocyclic scaffolds and bioactive intermediates, particularly in medicinal chemistry workflows requiring selective C-acylation or subsequent displacement reactions.
