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-5-chloro-4-hydroxybenzaldehyde features a trifunctional aromatic core with bromo, chloro, and hydroxyl groups positioned for orthogonal reactivity. This electron-deficient scaffold enables selective coupling in cross-coupling and Ullmann-type transformations. The aldehyde functionality offers direct access to imines and hydrazones under mild conditions. Bench-stable and moisture-tolerant, it serves as a key building block in the synthesis of bioactive heterocycles and functionalized polymers.

Application

3-Bromo-5-chloro-4-hydroxybenzaldehyde serves as a versatile building block for the synthesis of functionalized aromatic scaffolds. The aldehyde group enables direct coupling reactions, while the bromo and chloro substituents facilitate palladium-catalyzed cross-couplings. The phenolic hydroxyl supports derivatization and ortho-directed functionalization, enhancing its utility in medicinal chemistry and materials science applications.
