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.

Type	HazMat Fee
Excepted Quantity	$0.00
FedEx Limited Quantities Ground	$0.00
Hazmat Ground shipping	$50.00+
Inaccessible (Haz class 6.1 or 9), Domestic	$68.00+

Description

4-Bromo-5-chloro-2-fluorobenzaldehyde features a trifluorinated aromatic core with strategically positioned halogens, enabling direct coupling in cross-coupling reactions. The aldehyde group provides a reactive handle for nucleophilic addition or condensation chemistry, while the electron-deficient ring enhances electrophilicity for downstream functionalization. This compound serves as a key building block in pharmaceutical intermediates and advanced materials synthesis.

Application

4-Bromo-5-chloro-2-fluorobenzaldehyde serves as a versatile electrophilic building block in medicinal chemistry and materials science, enabling direct incorporation of halogenated aromatic motifs into complex molecular architectures. Its trifunctional substitution pattern—bromine, chlorine, and fluorine—confers enhanced metabolic stability and modulates electronic properties, while the aldehyde group facilitates nucleophilic additions, imine formations, and downstream functionalization. Bench-stable and compatible with standard cross-coupling protocols (e.g., Suzuki, Stille), it functions efficiently in late-stage diversification and heterocycle synthesis.
