    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

(R)-3,3'-Diiodo-[1,1'-binaphthalene]-2,2'-diol is a chiral scaffold featuring two iodine substituents flanking a rigid binaphthyl backbone and bearing hydroxyl groups at the 2,2' positions. This configuration enables robust coordination in asymmetric catalysis and provides a steric and electronic framework for transition metal complexation. The molecule exhibits enhanced stability under standard handling conditions and facilitates precise stereocontrol in synthetic transformations.

Application

(R)-3,3'-Diiodo-[1,1'-binaphthalene]-2,2'-diol serves as a chiral scaffold for asymmetric synthesis, enabling stereoselective transformations through its rigid binaphthyl framework and orthogonal iodide functionality. The diol group provides stability and facilitates purification, while the iodo substituents support palladium-catalyzed cross-coupling reactions, making it a practical building block for functionalized biaryl systems in catalysis and medicinal chemistry applications.
