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-Chloro-4-fluorobenzaldehyde features a strategically positioned aldehyde group flanked by chlorine and fluorine substituents, delivering enhanced electrophilicity and metabolic stability. This electron-deficient aromatic scaffold integrates readily into pharmaceutical intermediates and functional materials, offering predictable reactivity under standard conditions.

Application

3-Chloro-4-fluorobenzaldehyde serves as a valuable building block in medicinal chemistry and agrochemical synthesis, enabling efficient construction of fluorinated aromatic scaffolds. Its orthogonal halogen functionality facilitates palladium-catalyzed cross-coupling reactions, while the aldehyde group supports nucleophilic additions and imine formation. Bench-stable and readily purified by distillation, it offers predictable reactivity in multi-step syntheses.
