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

This tetraamine derivative features four amino groups on a conjugated dienone scaffold, enabling strong coordination with metal ions and facilitating redox-active applications. The electron-rich structure enhances reactivity in synthetic transformations, while the planar framework supports stable complex formation under standard conditions.

Application

2,3,5,6-Tetraaminocyclohexa-2,5-diene-1,4-dione serves as a versatile dihydroxyquinone-derived scaffold for the construction of bioactive heterocycles and metal-chelating ligands. Its four amino groups enable sequential functionalization, while the conjugated diketone system supports reductive amination and condensation reactions. Bench-stable and readily purified by recrystallization, it functions as a key building block in the synthesis of quinoline-based pharmaceutical intermediates and redox-active materials.
