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

Description

3-Bromo-5-chloro-2-fluorobenzaldehyde features a trifluorinated aromatic core with strategically positioned halogens enabling direct functionalization in cross-coupling reactions. The aldehyde group provides a reactive handle for nucleophilic additions and condensation processes, while the electron-deficient ring enhances electrophilicity at the carbonyl site. This compound serves as a key intermediate in the synthesis of pharmaceuticals and agrochemicals requiring tailored electronic and steric profiles.

Application

3-Bromo-5-chloro-2-fluorobenzaldehyde serves as a versatile building block for the synthesis of pharmaceutical intermediates and agrochemicals. Its orthogonal halogenation pattern enables selective cross-coupling reactions, while the aldehyde functionality facilitates imine formation, reductive amination, and derivatization under mild conditions. Bench-stable and compatible with standard purification protocols, it functions effectively in Pd-catalyzed couplings and heterocycle assembly.
