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-Methyl-5-nitropyridin-2(1H)-one features a fused heterocyclic core with a methyl group at the 4-position and a nitro substituent at the 5-position, delivering enhanced electron-withdrawing character. This configuration supports stable integration into pharmaceutical intermediates and functional materials, offering improved reactivity in nucleophilic substitution and coupling processes under standard conditions.

Application

4-Methyl-5-nitropyridin-2(1H)-one serves as a versatile building block in medicinal chemistry, enabling the construction of nitrogen-containing heterocycles via standard functional group manipulations. The nitro group facilitates reduction to an amine for downstream coupling or cyclization, while the pyridinone core provides a stable scaffold with moderate polarity, aiding purification and crystallization. Bench-stable and compatible with common reaction conditions, it functions effectively in multistep synthesis workflows requiring regioselective transformations.
