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+
Accessible (Haz class 3, 4, 5 or 8), Domestic	$158.00+
Inaccessible (Haz class 6.1 or 9), International	$108.00+

Description

(S,S)-Me-BI-DIME is a chiral bis(oxazoline) ligand featuring two methyl-substituted oxazoline rings, designed for asymmetric catalysis. This bench-stable, moisture-tolerant scaffold delivers high enantioselectivity in transition metal-catalyzed reactions, particularly in copper-mediated conjugate additions and cycloadditions. Its rigid, electron-rich architecture enables precise stereocontrol through well-defined coordination geometry.

Application

(S,S)-Me-BI-DIME serves as a robust chiral ligand in asymmetric catalysis, enabling high enantioselectivity in transition-metal-catalyzed transformations. Its bis-imine architecture provides excellent stereocontrol and bench stability, facilitating efficient synthesis of chiral building blocks. The methylated backbone enhances solubility and functional group tolerance, making it well-suited for scalable applications in medicinal chemistry and fine chemical synthesis.
