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

(S)-tBu-Pyox is a chiral pyridine-based oxazoline ligand featuring a bulky tert-butyl group that enhances steric control in asymmetric catalysis. This bench-stable, moisture-tolerant scaffold enables high enantioselectivity in transition metal-catalyzed transformations.

Application

(S)-tBu-Pyox serves as a highly effective chiral ligand in asymmetric catalysis, particularly enabling enantioselective transformations such as allylic alkylation and conjugate addition. Its robust t-butyl-substituted pyrrolidine core provides excellent steric control and bench stability, while the oxazoline moiety offers strong coordination to transition metals. This combination facilitates high enantioselectivity and reproducible results in scalable synthetic processes.
