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-Nitropyrazole features a nitro group at the para position relative to the pyrazole ring, imparting strong electron-withdrawing character and enhancing reactivity in heterocyclic synthesis. This bench-stable compound serves as a key intermediate in the development of bioactive molecules and functional materials.

Application

4-Nitropyrazole serves as a versatile heterocyclic building block in medicinal chemistry and agrochemical synthesis. The nitro group at the C4 position enables direct electrophilic substitution, facilitates subsequent reduction to an amine for further functionalization, and enhances reactivity in cross-coupling processes. Its bench-stable nature and compatibility with common protecting groups support efficient multi-step synthesis. This compound functions as a key scaffold for constructing bioactive molecules through well-established transformations.
