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 brominated benzo[b]fluorene features a sterically hindered, electron-deficient core ideal for palladium-catalyzed cross-coupling reactions. The 3-bromo substituent enables efficient functionalization under standard conditions, while the dimethyl groups enhance stability and solubility in organic media.

Application

3-Bromo-11,11-dimethyl-11H-benzo[b]fluorene serves as a versatile building block for the synthesis of polycyclic aromatic systems and functionalized heterocycles. The bromine at the 3-position enables palladium-catalyzed cross-coupling reactions with broad functional group tolerance. The sterically encumbered 11,11-dimethyl substitution enhances bench stability and reduces unwanted side reactions, facilitating purification and scalability in medicinal chemistry and materials science applications.
