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

(R)-C1-TunaPhos is a bench-stable, moisture-tolerant chiral phosphine ligand designed for palladium-catalyzed cross-coupling reactions. Featuring a sterically hindered aryl backbone and electron-rich phosphorus center, it enhances reaction efficiency and selectivity in asymmetric synthesis. This ligand integrates seamlessly into modern catalytic protocols requiring high enantiocontrol.

Application

(R)-C1-TunaPhos serves as a highly effective chiral ligand in palladium-catalyzed cross-coupling reactions, enabling enantioselective C–C bond formation with broad functional group tolerance. Its robust bench stability and ease of purification make it well-suited for scalable synthesis. The ligand facilitates high yields and excellent enantiomeric excess in Suzuki-Miyaura and Negishi couplings, particularly with aryl halides and triflates, offering reliable performance in complex molecule assembly.
