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-difluorobenzaldehyde features a strategically positioned aldehyde group flanked by bromine and two fluorine atoms, enabling direct incorporation into cross-coupling reactions. The electron-deficient aromatic ring enhances reactivity in palladium-catalyzed transformations, while the orthogonal functional handles support sequential derivatization. This bench-stable reagent streamlines access to complex fluorinated scaffolds for medicinal chemistry and materials synthesis.

Application

4-Bromo-2,3-difluorobenzaldehyde serves as a versatile building block in medicinal chemistry and agrochemical synthesis, enabling efficient Suzuki-Miyaura and Stille couplings due to its orthogonal halogen reactivity. The aldehyde functionality facilitates direct functionalization or oxime formation, while the fluorine substituents enhance metabolic stability and modulate electronic properties. Bench-stable and compatible with standard purification protocols, it functions reliably in multi-step synthetic sequences requiring selective transformation.
