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 diphenylphosphino-substituted oxazole integrates a reactive heterocyclic core with a versatile phosphine handle, enabling efficient coordination in transition metal catalysis. The dihydrooxazole ring provides structural rigidity and stability under standard conditions, while the para-phosphine moiety facilitates ligand assembly in palladium- and nickel-catalyzed cross-coupling reactions.

Application

2-[2-(Diphenylphosphino)phenyl]-4,5-dihydrooxazole serves as a versatile, bench-stable ligand precursor in palladium-catalyzed cross-coupling reactions. Its ortho-diphenylphosphinoaryl moiety enables efficient coordination to transition metals, facilitating C–C and C–heteroatom bond formations. The dihydrooxazole ring provides structural rigidity and enhances solubility, while the protected oxazole framework offers compatibility with diverse reaction conditions and simplifies purification.
