    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

Diethyl (2-(triethoxysilyl)ethyl)phosphonate integrates a reactive triethoxysilyl group with a phosphonate moiety, enabling covalent surface anchoring in silane-based functionalization. This bifunctional reagent facilitates robust coupling to oxide surfaces while maintaining compatibility with organic synthesis workflows.

Application

Diethyl (2-(triethoxysilyl)ethyl)phosphonate serves as a versatile silyl-protected phosphonate building block, enabling efficient incorporation of phosphonic acid functionalities into complex molecular architectures. Its triethoxysilyl group provides robust stability and facilitates downstream silane-directed transformations, including controlled hydrolysis and coupling reactions. The molecule exhibits excellent functional group tolerance and is compatible with standard synthetic workflows, making it ideal for constructing bioactive phosphonate analogs and surface-functionalized materials.
