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 rigid, chiral framework with two aryl groups at the 4- and 5-positions and a pyridin-2-yl substituent at C2, enabling precise spatial control in asymmetric synthesis. The fused heterocyclic core exhibits enhanced stability and facilitates directional interactions in catalytic systems and molecular recognition applications.

Application

(4R,5S)-4,5-Diphenyl-2-(pyridin-2-yl)-4,5-dihydrooxazole serves as a stable, bench-ready heterocyclic building block for the synthesis of complex nitrogen-containing scaffolds. Its defined stereochemistry and orthogonal functional groups enable reliable incorporation into medicinal chemistry campaigns, particularly in the construction of oxazoline-based ligands and bioactive intermediates. The molecule exhibits favorable handling properties, moderate solubility in common organic solvents, and compatibility with standard coupling and reduction protocols.
