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 oxazole scaffold features a diphenylphosphino group at the 2-position, enabling robust coordination in transition metal catalysis. The dihydrooxazole ring enhances solubility and stability under standard conditions, while the dimethyl substitution prevents undesired cyclization. This ligand integrates seamlessly into palladium-catalyzed cross-coupling systems, offering reliable performance in diverse synthetic workflows.

Application

2-[2-(Diphenylphosphino)phenyl]-4,5-dihydro-4,4-dimethyloxazole serves as a robust, bench-stable ligand for palladium-catalyzed cross-coupling reactions. Its rigid, electron-rich diphenylphosphino moiety enables efficient catalyst activation and enhances reactivity in Suzuki-Miyaura and Negishi couplings. The oxazole core provides steric protection and improved solubility, facilitating purification and scalability in synthetic workflows.
