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

2,6-Difluoro-4-nitrophenol delivers a potent electron-deficient aromatic scaffold featuring two fluorine substituents at the 2 and 6 positions, which enhance metabolic stability and influence regioselective reactivity. The para-nitro group serves as a strong acceptor, enabling efficient coupling in cross-coupling and nucleophilic substitution processes. This compound exhibits excellent bench stability and solubility in common organic solvents, facilitating use in synthetic workflows requiring precise electronic tuning.

Application

2,6-Difluoro-4-nitrophenol serves as a versatile building block in medicinal chemistry and agrochemical synthesis, enabling efficient access to fluorinated heterocycles and functionalized aromatic scaffolds. Its electron-deficient aromatic ring facilitates nucleophilic aromatic substitution, while the phenolic hydroxyl group allows for direct derivatization or protection. The molecule exhibits good bench stability and compatibility with standard purification techniques, making it well-suited for multi-step synthetic sequences requiring precise regiocontrol.
