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

2,2'-Dimethyl-1,1'-biphenyl features a sterically hindered biphenyl core with methyl groups at the ortho positions, enhancing stability and reducing rotational freedom. This configuration imparts excellent thermal resilience and resistance to oxidative degradation. The compound serves as a robust scaffold in ligand design, particularly in transition metal catalysis where steric bulk modulates reactivity and selectivity. Its bench-stable nature simplifies handling under standard laboratory conditions.

Application

2,2'-Dimethyl-1,1'-biphenyl serves as a robust, bench-stable biaryl building block for transition-metal-catalyzed coupling reactions. Its sterically hindered ortho-methyl groups enhance stability and reduce unwanted side reactions, enabling efficient Suzuki-Miyaura and Stille couplings. The molecule functions as a versatile scaffold in the synthesis of functionalized ligands and pharmaceutical intermediates, offering predictable reactivity and straightforward purification.
