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.

Type	HazMat Fee

Hazmat Ground shipping	$50.00+
Inaccessible (Haz class 6.1 or 9), Domestic	$68.00+

Description

This chiral bis-oxazole scaffold features a methylene bridge linking two dihydrooxazole rings, each bearing a tert-butyl substituent. The rigid, stereochemically defined structure enhances selectivity in asymmetric synthesis and serves as a robust ligand framework for transition metal catalysis under standard conditions.

Application

(4S,4'S)-2,2'-methylenebis[4,5-dihydro-4-(1-methylethyl)oxazole] serves as a chiral bis-oxazoline ligand enabling efficient asymmetric catalysis in transition-metal-mediated transformations. Its robust bench stability and defined stereochemistry facilitate reproducible enantioselective outcomes in C–C bond formation and metal-catalyzed additions. The structure supports broad functional group tolerance and simplifies purification, making it a practical choice for synthetic chemists developing stereoselective methodologies.
