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-Bromo-3-methylphenyl)ethanone features a brominated aromatic ring flanked by a methyl group and a ketone-bearing side chain, enabling direct integration into cross-coupling and functionalization workflows. The electron-deficient aryl moiety pairs effectively with palladium catalysts under standard conditions, while the bench-stable ketone offers a reliable handle for further derivatization in synthetic sequences.

Application

1-(4-Bromo-3-methylphenyl)ethanone serves as a versatile building block for the synthesis of biologically active molecules and pharmaceutical intermediates. Its structure features a brominated aromatic ring with a methyl group in close proximity to a ketone functionality, enabling selective functionalization via cross-coupling reactions. The ketone group provides a handle for further transformations such as reduction, nucleophilic addition, or enolization, while the aryl bromide supports palladium-catalyzed coupling processes. Bench-stable and readily purified by recrystallization or column chromatography, it integrates efficiently into multi-step synthetic sequences.
