    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

5,5'-Bis(trimethylstannyl)-2,2'-bithiophene features two trimethylstannyl groups flanking a bithiophene core, delivering high stability and exceptional reactivity in Stille coupling processes. This stannane moiety integrates readily into conjugated polymer architectures, enabling efficient construction of functional organic semiconductors with tailored electronic properties.

Application

5,5'-Bis(trimethylstannyl)-2,2'-bithiophene serves as a versatile Stannylation building block for the palladium-catalyzed construction of conjugated oligothiophenes and functionalized π-systems. Its stannyl groups enable efficient cross-coupling reactions with aryl halides and triflates under standard Suzuki-Miyaura conditions, offering high regioselectivity and excellent functional group tolerance. The molecule exhibits good bench stability and facilitates straightforward purification, making it well-suited for iterative synthesis of advanced materials and optoelectronic scaffolds.
