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

2-Bromo-9,9-dimethylfluorene features a sterically hindered fluorene core with a bromine substituent at the 2-position, enabling reliable coupling in palladium-catalyzed cross-coupling reactions. The dimethyl groups at the 9,9-positions enhance stability and reduce unwanted side reactions, making this compound well-suited for synthetic applications requiring robustness under standard conditions.

Application

2-Bromo-9,9-dimethylfluorene serves as a versatile building block in transition-metal-catalyzed coupling reactions, particularly in Suzuki and Stille couplings. Its sterically encumbered fluorenyl framework enhances stability and minimizes side reactions, while the bromo substituent enables reliable cross-coupling under standard conditions. The compound exhibits excellent bench stability and facilitates efficient purification, making it well-suited for applications in synthetic organic chemistry and materials science.
