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

rac-BI-DIME features a chiral bis-imidazole scaffold with enhanced solubility and bench stability, enabling efficient coordination in asymmetric catalysis. This robust ligand integrates seamlessly into transition metal complexes, delivering high enantioselectivity across diverse synthetic transformations.

Application

rac-BI-DIME functions as a robust, bench-stable chiral ligand for palladium-catalyzed cross-coupling reactions, enabling high-yielding C–C bond formations under mild conditions. Its rigid biaryl architecture provides excellent stereocontrol in asymmetric transformations, while its functional group tolerance supports diverse substrates. Widely used in the synthesis of pharmaceutically relevant scaffolds, rac-BI-DIME facilitates efficient access to complex molecular architectures with predictable enantioselectivity.
