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 chiral bisphosphine ligand features a Pybox backbone with (S,R) stereochemistry, delivering high enantioselectivity in transition metal catalysis. The rigid, electron-rich framework enhances coordination stability and facilitates asymmetric transformations under mild conditions.

Application

(S,R)-BisPh-Pybox serves as a highly effective chiral ligand in transition metal-catalyzed asymmetric synthesis, particularly for enantioselective transformations involving palladium and copper complexes. Its rigid, bidentate architecture with phenyl-substituted pyridine and oxazoline moieties enables high stereocontrol in C–C and C–heteroatom bond-forming reactions. The ligand exhibits excellent bench stability, ease of handling, and compatibility with diverse functional groups, making it a practical choice for scalable asymmetric catalysis in medicinal chemistry and fine chemical synthesis.
