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

3-Bromo-4,5-dihydroxybenzaldehyde features a brominated aromatic ring flanked by two adjacent hydroxyl groups and a formyl functionality. This configuration enables direct incorporation into bioactive molecule scaffolds, particularly in the synthesis of catechol-containing pharmaceuticals and fluorescent probes. The compound exhibits enhanced reactivity in electrophilic substitution and transition-metal-catalyzed coupling reactions due to synergistic electronic effects from the electron-donating hydroxyls and the electron-withdrawing bromine.

Application

3-Bromo-4,5-dihydroxybenzaldehyde serves as a versatile building block for the synthesis of bioactive heterocycles and natural product analogs. The ortho-dihydroxy motif enables facile metal-catalyzed coupling reactions and oxidative cyclizations, while the bromine substituent provides a reliable handle for palladium-mediated cross-coupling. Its bench-stable crystalline form facilitates handling and purification, making it well-suited for iterative synthetic campaigns in medicinal chemistry and process development.
