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 difluorocyclopropane carboxylic acid features a strained three-membered ring bearing two fluorine atoms and a phenyl group, conferring enhanced metabolic stability and lipophilicity. The carboxylic acid functionality enables direct derivatization or salt formation for improved solubility in synthetic and medicinal chemistry applications.

Application

2,2-Difluoro-1-phenylcyclopropane-1-carboxylic acid serves as a valuable building block in medicinal chemistry, enabling the incorporation of a rigid, electron-deficient cyclopropane motif into bioactive molecules. Its difluorocyclopropane core enhances metabolic stability and modulates lipophilicity, while the carboxylic acid functionality facilitates direct conjugation or derivatization in standard coupling reactions. The compound exhibits good bench stability and is compatible with diverse functional groups, making it well-suited for iterative synthesis and lead optimization workflows.
