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

4-Amino-3-nitrobenzaldehyde features a conjugated aldehyde group flanked by electron-donating amino and electron-withdrawing nitro substituents, enabling efficient coupling in cross-coupling and condensation reactions. This polarized structure enhances reactivity in synthesis of bioactive heterocycles and fluorescent probes under standard conditions.

Application

4-Amino-3-nitrobenzaldehyde serves as a versatile building block in synthetic organic chemistry, enabling the construction of heterocyclic scaffolds and functionalized aromatic systems. Its ortho-difunctionalized structure facilitates sequential transformations, including reductive coupling, nucleophilic substitution, and condensation reactions. The aldehyde group offers direct access to imines and hydrazones, while the amino and nitro groups provide complementary handles for selective derivatization. Bench-stable and readily purified by recrystallization, it supports scalable synthesis in medicinal chemistry and materials science applications.
