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

4'-Bromo-2',3'-difluoroacetophenone features a bromine atom at the 4' position and two fluorine substituents at the 2' and 3' positions on the phenyl ring, creating a highly electron-deficient aryl moiety. This configuration enhances reactivity in cross-coupling transformations and facilitates incorporation into complex molecular architectures requiring precise electronic tuning. The compound exhibits excellent stability under standard handling conditions and is compatible with palladium-catalyzed reactions.

Application

4'-Bromo-2',3'-difluoroacetophenone serves as a versatile building block in medicinal chemistry and agrochemical synthesis, enabling efficient late-stage functionalization via cross-coupling reactions. The bromo group facilitates Suzuki, Stille, or Negishi coupling, while the ortho-difluoro substitution enhances metabolic stability and modulates electronic properties. Its bench-stable crystalline form allows for straightforward handling and purification, making it ideal for iterative scaffold diversification in target-oriented synthesis.
