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

3-Chlorobicyclo[1.1.1]pentane-1-carboxylic acid is a rigid, electron-deficient scaffold featuring a strained bicyclic core with a pendant carboxylic acid group. This configuration enables direct incorporation into bioactive molecules, where the chlorinated cage imparts metabolic stability and modulates electronic properties. The compound serves as a valuable building block in medicinal chemistry for probing steric and electronic effects in target-directed ligand design.

Application

3-Chlorobicyclo[1.1.1]pentane-1-carboxylic acid serves as a rigid, sterically constrained building block for medicinal chemistry and target-oriented synthesis. Its strained bicyclic core imparts high metabolic stability and enhances bioavailability when incorporated into molecular scaffolds. The carboxylic acid functionality enables direct derivatization via amide coupling or esterification, while the chlorine substituent offers a handle for further functionalization through nucleophilic substitution or cross-coupling reactions. The compound exhibits excellent bench stability and compatibility with standard purification techniques.
