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-chlorobenzaldehyde features a dual-halo substitution pattern on the benzene ring, delivering enhanced reactivity in cross-coupling transformations. The aldehyde group enables direct functionalization or conjugation, while the ortho-bromine and meta-chlorine substituents provide orthogonal handles for sequential derivatization under standard palladium-catalyzed conditions. This compound serves as a high-purity building block for advanced synthetic intermediates in medicinal chemistry and materials science.

Application

3-Bromo-4-chlorobenzaldehyde serves as a versatile building block in medicinal chemistry and agrochemical synthesis, enabling palladium-catalyzed cross-coupling reactions due to its orthogonal halogen reactivity. The aldehyde functionality facilitates imine formation, reductive amination, and oxime derivatization, while the bromo and chloro substituents offer complementary sites for selective functionalization. Bench-stable and compatible with standard purification methods, it functions reliably in multi-step syntheses requiring precise regiocontrol.
