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

2-Methylbenzophenone is a sterically hindered ketone featuring a methyl group at the ortho position relative to the carbonyl. This substitution enhances stability and modulates reactivity, making it valuable in photoredox catalysis and organic synthesis. The compound exhibits robust bench stability and facilitates selective transformations under mild conditions.

Application

2-Methylbenzophenone serves as a versatile building block in synthetic organic chemistry, enabling the construction of biaryl and heterocyclic scaffolds through palladium-catalyzed cross-coupling reactions. Its methyl substituent enhances regioselectivity in electrophilic aromatic substitution and provides steric bias in transition metal-mediated transformations. The ketone functionality offers direct access to α-alkylated derivatives and facilitates downstream functionalization via enolization or reduction. Bench-stable and readily purified by recrystallization, it functions reliably in multi-step syntheses targeting pharmaceutical intermediates and agrochemicals.
