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 chiral backbone with dual aryl substituents and a diphenylphosphino group positioned ortho to the heterocycle, enabling effective coordination in asymmetric catalysis. The rigid, electron-rich architecture supports stable complexation with transition metals, facilitating enantioselective transformations under standard conditions.

Application

(4R,5R)-2-(2-(Diphenylphosphino)phenyl)-4,5-diphenyl-4,5-dihydrooxazole serves as a versatile chiral ligand scaffold in transition metal catalysis, enabling asymmetric synthesis through well-established palladium- and rhodium-catalyzed transformations. Its rigid, electron-rich diphenylphosphinoaryl moiety facilitates efficient coordination to metal centers, while the dihydrooxazole ring provides stereochemical control and enhanced bench stability. This compound functions effectively in cross-coupling reactions and enantioselective hydrogenation processes, offering predictable reactivity and straightforward purification in industrial R&D workflows.
