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-2,5-dimethoxybenzaldehyde features a bromine substituent at the para position relative to the aldehyde, flanked by two methoxy groups that enhance electron density. This combination enables selective coupling reactions in synthetic routes to bioactive compounds. The molecule exhibits bench-stable handling characteristics and compatibility with standard reaction conditions in medicinal chemistry workflows.

Application

4-Bromo-2,5-dimethoxybenzaldehyde serves as a versatile building block in medicinal chemistry and heterocyclic synthesis. Its bromo group enables palladium-catalyzed cross-coupling reactions, while the two methoxy groups provide orthogonally protected phenolic sites. The aldehyde functionality facilitates condensation reactions and imine formation, supporting rapid access to diverse scaffolds. Bench-stable and amenable to standard purification methods, it functions effectively in multi-step syntheses requiring functional group compatibility and predictable reactivity.
