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

(S,S)-BenzP features a chiral bis(phenyl) backbone with defined stereochemistry, enabling precise asymmetric synthesis. This bench-stable, moisture-tolerant ligand integrates seamlessly into transition-metal catalysis workflows, delivering high enantioselectivity in cross-coupling and reduction reactions.

Application

(S,S)-BenzP serves as a robust chiral ligand in asymmetric catalysis, enabling high enantioselectivity in transition-metal-catalyzed reactions. Its rigid binaphthyl backbone and well-defined stereogenic centers provide excellent stereocontrol in palladium- and rhodium-catalyzed transformations. The ligand exhibits good bench stability, facile handling, and compatibility with diverse functional groups, making it a practical choice for synthetic routes to chiral building blocks and active pharmaceutical ingredients.
