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-nitrobenzaldehyde features a chlorine substituent at the meta position and a nitro group at the ortho position relative to the aldehyde, creating a strongly electron-deficient aromatic ring. This configuration enhances reactivity in nucleophilic addition and condensation reactions. The compound exhibits bench-stable handling characteristics and integrates readily into complex synthetic sequences requiring polarized carbonyl functionality.

Application

5-Chloro-2-nitrobenzaldehyde serves as a versatile building block in medicinal chemistry and agrochemical synthesis, enabling efficient access to substituted heterocycles via condensation and cyclization reactions. Its electron-deficient aromatic core enhances reactivity in nucleophilic aromatic substitution, while the aldehyde and nitro groups provide orthogonal functional handles for sequential transformations. Bench-stable and readily purified by recrystallization, it facilitates scalable synthesis of complex scaffolds.
