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

4-Chloro-2-fluoro-5-nitrobenzaldehyde features a trifunctional aromatic core integrating electron-withdrawing halogens and a nitro group, enabling efficient coupling in cross-coupling and multistep synthesis. This bench-stable aldehyde integrates readily into pharmaceutical intermediates and functional materials, offering high reactivity under standard conditions.

Application

4-Chloro-2-fluoro-5-nitrobenzaldehyde serves as a versatile building block in medicinal chemistry and agrochemical synthesis, enabling efficient access to substituted heterocycles via electrophilic aromatic substitution and coupling reactions. Its ortho-fluoro and para-chloro directing groups facilitate regioselective functionalization, while the aldehyde and nitro functionalities offer complementary handles for downstream transformations. Bench-stable and compatible with standard reaction conditions, it functions effectively in multi-step syntheses requiring precise positional control.
