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.

Type	HazMat Fee
Excepted Quantity	$0.00
FedEx Limited Quantities Ground	$0.00
Hazmat Ground shipping	$50.00+
Inaccessible (Haz class 6.1 or 9), Domestic	$68.00+

Description

This chiral cyclopropane carboxylic acid features a rigid, strained ring system with two fluorine atoms at the geminal 2-position, conferring enhanced metabolic stability and distinct electronic properties. The (1R) stereochemistry enables selective incorporation into bioactive molecules, particularly in medicinal chemistry applications where conformational restraint and lipophilicity are critical.

Application

(1R)-2,2-Difluorocyclopropane-1-carboxylic acid serves as a conformationally constrained building block for medicinal chemistry campaigns, enabling the exploration of stereochemically defined bioactive scaffolds. Its rigid cyclopropane core imparts metabolic stability and enhances target binding affinity in peptidomimetic and CNS-targeted compound development. The difluoro substitution pattern modulates electronic properties and lipophilicity, while the carboxylic acid group facilitates direct derivatization or salt formation. Bench-stable and compatible with standard coupling protocols, it functions effectively in solid-phase synthesis and fragment-based drug discovery workflows.
