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 diamine features a rigid biphenyl backbone with sterically shielded N-methyl groups, delivering high enantioselectivity in asymmetric catalysis. The (1S,2S) configuration ensures predictable stereochemical control, while the electron-rich aromatic system enhances ligand-metal interactions. Bench-stable and readily handled under standard conditions, it integrates seamlessly into transition metal complexes for synthetic applications requiring precise stereocontrol.

Application

(1S,2S)-N1,N1,N2,N2-Tetramethyl-1,2-diphenylethane-1,2-diamine serves as a chiral diamine ligand in asymmetric catalysis, enabling high enantioselectivity in transition metal-catalyzed reactions. Its rigid biphenyl backbone and sterically encumbered N-methyl groups provide excellent stereocontrol and bench stability. The compound facilitates efficient coordination to metals such as Cu(II) and Ni(II), making it valuable for C–C and C–heteroatom bond-forming processes in synthetic organic chemistry.
