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

2,2'-Bithiophene-5,5'-dicarboxaldehyde features two electron-rich thiophene rings linked by a direct bond, bearing aldehyde groups at the 5-positions. This planar, conjugated scaffold enables efficient π-extension in organic semiconductors and facilitates coupling reactions for functionalized materials in optoelectronic applications.

Application

2,2'-Bithiophene-5,5'-dicarboxaldehyde serves as a versatile building block for conjugated materials, enabling efficient synthesis of π-extended heterocycles via condensation and coupling reactions. Its dual aldehyde functionality offers high reactivity in imine formation, Staudinger ligation, and transition-metal-catalyzed cross-couplings, facilitating the construction of functionalized oligothiophenes and donor-acceptor architectures. Bench-stable and readily purified by recrystallization, it supports scalable access to advanced electronic materials.
