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+
Inaccessible (Haz class 6.1 or 9), International	$108.00+

Description

[2,2':5',2''-Terthiophene]-5-carbaldehyde features a linear, electron-rich terthiophene backbone with a terminal aldehyde group enabling direct functionalization. This conjugated scaffold delivers enhanced charge transport properties and facilitates incorporation into organic semiconductors, photovoltaic materials, and molecular electronics architectures.

Application

[2,2':5',2''-Terthiophene]-5-carbaldehyde serves as a versatile building block for conjugated materials, enabling efficient coupling reactions via its aldehyde functionality. Its planar, electron-rich terthiophene backbone enhances charge transport properties, while the terminal aldehyde allows for straightforward derivatization—such as reductive amination or cyanohydrin formation—facilitating access to functionalized oligothiophenes and advanced organic semiconductors. Bench-stable and compatible with standard synthetic protocols, it supports scalable synthesis of tailored π-conjugated architectures.
