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

Tetrakis[μ-(2S)-3,3-dimethyl-2-(phthalimido)butanoato-κO,O]dirhodium features a chiral bis(β-amino acid) ligand framework that stabilizes the dirhodium core, enabling selective C–H functionalization. The phthalimido group enhances solubility and electronic modulation, while the sterically shielded dimethyl substituents reduce unwanted side reactions. This complex operates reliably under standard conditions in catalytic transformations requiring high enantioselectivity.

Application

Tetrakis[μ-(2S)-3,3-dimethyl-2-(phthalimido)butanoato-κO,O]dirhodium serves as a highly effective dirhodium catalyst for carbene transfer reactions, enabling efficient cycloadditions and C–H functionalizations. Its chiral ligand framework provides excellent stereocontrol in asymmetric synthesis, while the phthalimide group enhances solubility and stability under standard reaction conditions. The complex demonstrates robust performance across diverse substrates, facilitating clean transformations with minimal decomposition—ideal for scalable benchtop applications in medicinal chemistry and natural product synthesis.
