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.

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

Description

(R,S)-Bn-BisPh-Sabox delivers a chiral bisphosphine scaffold with benzyl-protected phosphorus centers, enabling robust coordination in asymmetric catalysis. The stereochemically defined backbone supports high enantioselectivity in transition-metal-catalyzed transformations, particularly in cross-coupling and hydrogenation processes. This bench-stable ligand features enhanced solubility in organic media and tolerates air during handling, streamlining synthetic workflows.

Application

(R,S)-Bn-BisPh-Sabox serves as a robust chiral ligand for asymmetric catalysis, enabling high enantioselectivity in transition-metal-catalyzed transformations. Its benzyl-protected bisphosphine architecture offers excellent bench stability and functional group tolerance, facilitating efficient synthesis of enantiomerically enriched intermediates. Widely applicable in cross-coupling and hydrogenation protocols, it functions reliably across diverse reaction conditions, making it a practical choice for industrial and academic R&D workflows.
