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+
Accessible (Haz class 3, 4, 5 or 8), Domestic	$158.00+

Description

2-Bromo-9H-fluoren-9-one is a brominated fluorenone derivative featuring a reactive ketone group and a pendant bromide at the 2-position. This compound serves as a key intermediate in synthetic organic chemistry, particularly in palladium-catalyzed cross-coupling reactions. The electron-deficient fluorenone core enhances reactivity in nucleophilic substitutions, while the bromo substituent enables further functionalization via coupling protocols. Its bench-stable nature supports reliable handling under standard conditions.

Application

2-Bromo-9H-fluoren-9-one serves as a versatile building block in synthetic organic chemistry, enabling efficient construction of fused heterocycles and functionalized fluorene scaffolds. Its electrophilic bromine and ketone functionalities support diverse transformations including nucleophilic substitution, Suzuki coupling, and enolate-mediated C–C bond formation. The compound exhibits excellent bench stability and facilitates straightforward purification, making it well-suited for both medicinal chemistry campaigns and process-scale synthesis.
