    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

Tetramethylol acetylenediurea offers a robust, moisture-tolerant platform for crosslinking applications. Featuring four hydroxyl groups attached to a rigid acetylene core, it enables efficient network formation under mild conditions. This structure enhances thermal stability and resistance to hydrolysis in resin systems.

Application

Tetramethylol acetylenediurea serves as a versatile, bench-stable building block for the synthesis of functionalized heterocycles and polyfunctional intermediates. Its four hydroxyl groups enable efficient derivatization via esterification or etherification, while the acetylenic linkage supports selective coupling reactions. The molecule demonstrates excellent functional group tolerance and facilitates straightforward purification, making it well-suited for iterative synthetic workflows in medicinal chemistry and materials development.
