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.

FedEx Limited Quantities Ground	$0.00
Hazmat Ground shipping	$50.00+
Inaccessible (Haz class 6.1 or 9), Domestic	$68.00+

Description

(S)-2,2'-Bis[bis(3,5-dimethylphenyl)phosphino]-4,4',6,6'-tetramethoxy-1,1'-biphenyl is a sterically hindered, electron-rich chiral ligand featuring four methoxy groups that enhance solubility and stability. This configuration enables efficient coordination in palladium-catalyzed cross-coupling reactions, delivering high selectivity and turnover under mild conditions.

Application

(S)-2,2'-Bis[bis(3,5-dimethylphenyl)phosphino]-4,4',6,6'-tetramethoxy-1,1'-biphenyl serves as a sterically encumbered, electron-rich phosphine ligand that enables efficient palladium-catalyzed cross-coupling reactions. Its orthogonal methoxy groups enhance solubility and stability, while the chiral backbone provides stereocontrol in asymmetric transformations. Functions effectively in Suzuki-Miyaura, Negishi, and Stille couplings under mild conditions, offering high yields and reproducibility in complex molecule synthesis.
