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

5-Bromo-2-chlorobenzaldehyde features a strategically positioned aldehyde group flanked by bromo and chloro substituents, enabling direct incorporation into cross-coupling reactions. This electron-deficient aromatic scaffold offers enhanced reactivity in palladium-catalyzed transformations and provides a robust platform for synthesizing complex pharmaceutical intermediates under standard conditions.

Application

5-Bromo-2-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 downstream transformations such as reductive amination and Wittig reactions, while the bromo and chloro substituents offer complementary sites for sequential functionalization. Bench-stable and readily purified by distillation or chromatography, it functions reliably in multi-step syntheses requiring precise regiocontrol.
