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

3-Chloro-5-fluorophenol features a phenolic hydroxyl group flanked by chlorine and fluorine substituents, delivering enhanced electron-withdrawal and metabolic stability. This combination enables selective reactivity in pharmaceutical intermediates and agrochemical synthesis, particularly in coupling reactions requiring halogen-directed functionalization.

Application

3-Chloro-5-fluorophenol serves as a versatile building block in medicinal chemistry and agrochemical synthesis, enabling selective functionalization at the phenolic hydroxyl group. Its electron-withdrawing halogen substituents enhance reactivity in nucleophilic aromatic substitution and facilitate coupling reactions via Pd-catalyzed cross-coupling protocols. The compound exhibits good bench stability and is compatible with common protecting group strategies, supporting efficient route design for complex heterocyclic scaffolds and API intermediates.
