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.

Type	HazMat Fee
Excepted Quantity	$0.00
FedEx Limited Quantities Ground	$0.00
Hazmat Ground shipping	$50.00+
Inaccessible (Haz class 6.1 or 9), Domestic	$68.00+
Accessible (Haz class 3, 4, 5 or 8), Domestic	$158.00+

Description

4,4-Bis(2-ethylhexyl)-4H-cyclopenta[1,2-b:5,4-b']dithiophene is a sterically shielded, electron-rich fused thiophene derivative designed for high-performance organic semiconductors. The branched alkyl chains enhance solubility and film-forming properties while maintaining robust charge transport characteristics. This structure enables efficient integration into solution-processable devices such as organic field-effect transistors and solar cells.

Application

4,4-Bis(2-ethylhexyl)-4H-cyclopenta[1,2-b:5,4-b']dithiophene serves as a robust, bench-stable building block for conjugated polymers and small-molecule semiconductors. Its alkyl-substituted dithiophene core enables excellent solubility, processability, and film-forming properties, while maintaining high charge carrier mobility in organic electronic devices. Functions effectively in Pd-catalyzed cross-coupling reactions and serves as a key unit in donor–acceptor architectures for solution-processable photovoltaics and transistors.
