    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

Tetramethylcyclobutane-1,3-dione features two carbonyl groups flanked by methyl substituents on a strained cyclobutane ring, enhancing its reactivity in cycloaddition and condensation reactions. This electron-deficient scaffold serves as a robust building block for synthesizing complex heterocycles and natural product analogs under standard conditions.

Application

Tetramethylcyclobutane-1,3-dione serves as a versatile synthon in organic synthesis, enabling efficient construction of substituted cyclohexane and pyran scaffolds via Diels-Alder reactions. Its enhanced stability and defined regiochemistry facilitate reliable heterocycle formation under mild conditions. The molecule’s four methyl groups provide steric protection and improve solubility, simplifying purification and enhancing compatibility with diverse functional groups in multi-step sequences.
