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

4,9-Dihydro-s-indaceno[1,2-b:5,6-b']dithiophene is a planar, electron-rich heterocycle featuring fused thiophene units that enhance charge transport properties. This robust scaffold integrates readily into conjugated systems, offering high stability and favorable redox behavior for organic semiconductors and optoelectronic applications.

Application

4,9-Dihydro-s-indaceno[1,2-b:5,6-b']dithiophene serves as a robust, bench-stable building block for conjugated materials, enabling efficient access to fused thiophene architectures via standard oxidative cyclization. Its planar, electron-rich core facilitates high charge carrier mobility and demonstrates excellent functional group tolerance in Pd-catalyzed cross-coupling reactions, making it ideal for the synthesis of organic semiconductors and donor-acceptor copolymers.
