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 sulfinamide ligand integrates a diphenylphosphinoaryl moiety with a sterically hindered tert-butyl sulfonamide group, enabling precise stereocontrol in asymmetric catalysis. Its rigid backbone and defined stereogenic center facilitate high enantioselectivity across diverse transition-metal-catalyzed transformations.

Application

[S(R)]-N-[(R)-[2-(Diphenylphosphino)phenyl]phenylmethyl]-2-methyl-2-propanesulfinamide serves as a chiral auxiliary in asymmetric synthesis, enabling stereoselective transformations through its well-defined stereochemistry and stable sulfinamide functionality. The diphenylphosphino group enhances coordination capability in transition metal-catalyzed reactions, while the tert-butylsulfinamide moiety facilitates efficient enolate formation and subsequent C–C bond construction. This scaffold exhibits excellent bench stability, predictable stereochemical outcomes, and compatibility with standard purification methods, making it a reliable building block for complex molecular architectures in medicinal chemistry and process development.
