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-Methylbenzophenone is a sterically hindered aryl ketone featuring a methyl group at the meta position relative to the carbonyl. This substitution enhances stability and modulates reactivity in electrophilic aromatic substitution, making it valuable for synthesizing complex organic frameworks under standard conditions.

Application

3-Methylbenzophenone serves as a versatile building block in synthetic organic chemistry, enabling efficient access to substituted biphenyls and functionalized heterocycles. Its methyl group provides a site for directed ortho-metalation, while the ketone functions as a key electrophilic handle in nucleophilic additions and conjugate reactions. Bench-stable and readily purified by recrystallization, it supports scalable synthesis in medicinal chemistry and materials research.
