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

2-Bromo-7-iodo-9,9-dimethyl-9H-fluorene features a sterically hindered fluorene core with orthogonal halogen handles, enabling selective cross-coupling under standard conditions. The dimethyl substitution enhances stability and solubility, while the bromo and iodo groups facilitate sequential functionalization in palladium-catalyzed reactions.

Application

2-Bromo-7-iodo-9,9-dimethyl-9H-fluorene serves as a versatile bifunctional building block in cross-coupling chemistry, enabling sequential Pd-catalyzed transformations. The bromo and iodo substituents exhibit orthogonal reactivity, facilitating selective functionalization in complex molecule assembly. The sterically encumbered 9,9-dimethylfluorene core enhances stability and simplifies purification. This compound functions reliably in Suzuki-Miyaura, Stille, and Negishi couplings, making it valuable for synthesizing conjugated materials and medicinally relevant heterocyclic scaffolds.
