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 cyclopenta[2,1-b:3,4-b']dithiophene features two bromine atoms at the 2 and 6 positions and sterically bulky 2-ethylhexyl groups at the 4-positions, enhancing solubility and processability. The electron-rich core supports efficient charge transport in organic semiconductors, enabling integration into solution-processable thin-film devices with high stability under ambient conditions.

Application

2,6-Dibromo-4,4-bis(2-ethylhexyl)-4H-cyclopenta[2,1-b:3,4-b']dithiophene serves as a key building block for high-performance organic semiconductors. The dibromo functionality enables efficient Suzuki and Stille coupling reactions, facilitating the construction of conjugated polymers and oligomers with tunable electronic properties. Its bis(2-ethylhexyl) substituents enhance solubility and film-forming characteristics, supporting solution-processable device fabrication. The molecule exhibits excellent bench stability and compatibility with standard synthetic protocols, making it ideal for industrial R&D in organic electronics.
