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-fluoro-5-methoxybenzaldehyde features a trifunctional aromatic core enabling direct incorporation into Suzuki-Miyaura and Ullmann coupling cascades. The electron-deficient aldehyde group pairs with ortho-fluorine for selective cross-coupling, while the methoxy substituent enhances solubility and modulates reactivity under standard conditions.

Application

4-Bromo-2-fluoro-5-methoxybenzaldehyde serves as a versatile building block in medicinal chemistry and agrochemical synthesis, enabling the construction of substituted heterocycles via standard coupling reactions. Its ortho-fluoro and para-bromo substituents facilitate palladium-catalyzed cross-couplings, while the methoxy and aldehyde groups offer orthogonal functionalization potential. The compound exhibits good bench stability and is amenable to purification by crystallization or flash chromatography, supporting efficient integration into multi-step synthetic sequences.
