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-fluoronitrobenzene is a bifunctional aromatic electrophile featuring complementary leaving groups for sequential substitution. This electron-deficient aryl halide enables efficient coupling reactions in late-stage functionalization, particularly in the synthesis of complex heterocycles and pharmaceutical intermediates. The ortho-chloro and para-fluoro substituents facilitate regioselective nucleophilic displacement under mild conditions.

Application

2-Chloro-4-fluoronitrobenzene serves as a versatile electrophilic building block in nucleophilic aromatic substitution (SNAr) reactions, enabling efficient construction of complex heterocycles and pharmaceutical intermediates. Its complementary halogen and fluorine substituents facilitate selective functionalization under mild conditions, while maintaining bench stability and ease of purification.
