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

1-(4-Chloro-2-(trifluoromethyl)phenyl)ethanone features a trifluoromethyl-substituted aryl ring coupled to a ketone-bearing ethyl side chain, delivering enhanced electron-withdrawing character and improved metabolic stability. This configuration supports efficient incorporation into pharmaceutical intermediates and functional materials, particularly in heterocyclic synthesis and transition-metal-catalyzed coupling reactions under standard conditions.

Application

1-(4-Chloro-2-(trifluoromethyl)phenyl)ethanone serves as a versatile building block in medicinal chemistry, enabling the construction of biologically relevant aryl ketones. Its trifluoromethyl and chloro substituents enhance metabolic stability and modulate electronic properties. The ketone functionality facilitates nucleophilic additions, reductive aminations, and coupling reactions, offering reliable access to diverse heterocyclic scaffolds and API intermediates. Bench-stable and amenable to standard purification techniques, it functions effectively in multi-step syntheses.
