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

This brominated acetophenone derivative features a methoxy-substituted aromatic ring and a reactive ketone group, enabling direct functionalization in cross-coupling and conjugate addition reactions. The para-positioned bromine facilitates palladium-catalyzed transformations, while the ortho-methoxy group enhances solubility and modulates electronic effects. This bench-stable compound serves as a key intermediate in medicinal chemistry and materials synthesis.

Application

1-(3-Bromo-2-methoxyphenyl)ethanone serves as a versatile building block in medicinal chemistry, enabling palladium-catalyzed cross-coupling reactions due to its well-defined aryl bromide functionality. The ketone group provides a handle for further functionalization, while the methoxy substituent enhances solubility and modulates electronic properties. Bench-stable and compatible with standard purification methods, it facilitates efficient synthesis of complex heterocyclic scaffolds and API intermediates.
