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-Nitro-2(1H)-pyridinone is a bench-stable, electron-deficient heterocycle featuring a strategically positioned nitro group that enhances reactivity in nucleophilic substitution and transition metal-catalyzed coupling processes. This nitrogen-rich scaffold integrates readily into bioactive molecules and functional materials, offering predictable regiochemistry and compatibility with diverse reaction conditions.

Application

4-Nitro-2(1H)-pyridinone serves as a versatile building block in medicinal and synthetic chemistry, enabling efficient access to nitrogen-rich heterocyclic scaffolds. Its dual functionality—electron-deficient pyridinone core and readily reducible nitro group—facilitates diverse transformations, including palladium-catalyzed couplings and reductive functionalization. The compound exhibits good bench stability and compatibility with common protecting group strategies, supporting its use in multi-step synthesis of API intermediates and targeted libraries.
