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-Chloro-4-fluoro-5-nitroaniline features a trifunctional aromatic core with electron-withdrawing halogens and a nitro group, enabling precise coupling in pharmaceutical intermediates. This bench-stable derivative integrates readily into complex scaffolds under standard conditions.

Application

2-Chloro-4-fluoro-5-nitroaniline serves as a key intermediate in the synthesis of bioactive heterocycles and pharmaceutical scaffolds. Its electron-deficient aromatic core enables efficient coupling reactions, while the orthogonal reactivity of the chloro, fluoro, and nitro groups facilitates sequential functionalization. Bench-stable and compatible with standard purification methods, it functions effectively in cross-coupling, nucleophilic substitution, and reduction protocols essential to medicinal chemistry workflows.
