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

Bis((R)-4-(tert-butyl)-4,5-dihydrooxazol-2-yl)methane features a chiral bis-oxazoline scaffold with steric shielding from bulky tert-butyl groups. This bench-stable ligand integrates readily into transition metal complexes, delivering high enantioselectivity in asymmetric catalysis. The rigid yet flexible framework enables precise control over coordination geometry.

Application

Bis((R)-4-(tert-butyl)-4,5-dihydrooxazol-2-yl)methane serves as a robust chiral auxiliary in asymmetric synthesis, enabling stereoselective transformations through its stable oxazoline framework. The tert-butyl group enhances steric bulk and bench stability, while the dihydrooxazoline moieties offer predictable reactivity in enantioselective additions and metal-catalyzed couplings. Its compatibility with standard purification methods and functional group tolerance make it a practical choice for iterative synthesis workflows.
