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.

Application

(1S,2S)-N,N'-Dimethyl-1,2-diphenylethylenediamine serves as a chiral diamine ligand in asymmetric catalysis, enabling enantioselective transformations such as hydrogenation and conjugate addition. Its rigid biphenyl backbone and defined stereochemistry provide high diastereoselectivity in transition-metal-catalyzed reactions. The N-methyl groups enhance solubility and reduce basicity, improving functional group tolerance and simplifying purification. This robust scaffold is widely employed in the synthesis of chiral intermediates for pharmaceuticals and fine chemicals.
