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 bicyclic alkene features two benzhydryl groups at the 5,6-positions, creating a sterically congested, electron-rich framework ideal for asymmetric synthesis. The rigid, chiral scaffold enables controlled stereochemical outcomes in cycloaddition and transition-metal-catalyzed reactions under standard conditions.

Application

(1R,4S,5S,6S)-5,6-Dibenzhydrylbicyclo[2.2.1]hept-2-ene serves as a rigid, sterically defined tricyclic scaffold enabling controlled stereochemical outcomes in asymmetric synthesis. Its stable, bench-compatible structure facilitates Diels-Alder cycloadditions and functions as a versatile building block for complex molecular architectures. The dibenzhydryl substitution enhances solubility and stability, simplifying purification while maintaining high functional group tolerance in standard organic transformations.
