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 cyclopropanamine features a rigid, strained three-membered ring system with defined stereochemistry at the 1R,2S configuration. The phenyl group imparts aromatic character and steric influence, while the primary amine enables facile derivatization. Ideal for asymmetric synthesis and medicinal chemistry applications requiring conformational constraint and precise spatial orientation.

Application

(1R,2S)-2-Phenylcyclopropan-1-amine serves as a stereochemically defined building block for bioactive molecule synthesis, offering high functional group tolerance and bench stability. Its constrained cyclopropane scaffold enables precise spatial orientation in medicinal chemistry applications, facilitating efficient coupling reactions and serving as a key intermediate in the construction of heterocyclic frameworks relevant to CNS-targeted therapeutics.
