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-Chloro-2,4-difluorobenzaldehyde features a trifluorinated aromatic core with orthogonal electron-withdrawing substituents that enhance reactivity in nucleophilic addition and transition-metal-catalyzed coupling processes. This bench-stable aldehyde integrates readily into complex molecular architectures under standard conditions.

Application

5-Chloro-2,4-difluorobenzaldehyde serves as a versatile building block in medicinal chemistry and agrochemical synthesis, enabling efficient construction of heterocyclic scaffolds via nucleophilic addition and condensation reactions. Its electron-deficient aromatic core enhances reactivity in Suzuki-Miyaura and Buchwald-Hartwig couplings, while the aldehyde functionality permits facile derivatization. Bench-stable and readily purified by distillation or recrystallization, it offers predictable performance in multi-step syntheses requiring functional group tolerance and compatibility with common protecting groups.
