    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

3,9-Bis(octadecyloxy)-2,4,8,10-tetraoxa-3,9-diphosphaspiro[5.5]undecane is a diphosphaspiro compound which contains two phosphorus atoms and can be used as an antioxidant and as a reducing agent.Color stabilizer for polymers

Application

3,9-Bis(octadecyloxy)-2,4,8,10-tetraoxa-3,9-diphosphaspiro[5.5]undecane serves as a stable, bench-ready phosphorus-containing building block for the synthesis of functionalized heterocycles and phosphine ligands. Its spirocyclic architecture provides enhanced thermal stability and facilitates selective functionalization at the phosphorus centers. The long alkoxy chains improve solubility in organic media and support compatibility with standard purification protocols. This compound enables efficient access to complex phosphorus heterocycles and functionalized scaffolds relevant to catalytic systems and materials chemistry.
