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+
Accessible (Haz class 3, 4, 5 or 8), International	$238.00+

Description

Benzo[1,2-b:3,4-b':5,6-b'']trithiophene-2,5,8-tricarbaldehyde features three aldehyde groups positioned at the 2, 5, and 8 ring junctions of a rigid, electron-deficient fused thiophene core. This configuration enables efficient π-conjugation extension and facilitates directional coupling in organic semiconductor architectures. The aldehyde functionalities serve as reactive handles for imine formation or reductive amination, supporting modular assembly of functionalized donor–acceptor systems.

Application

Benzo[1,2-b:3,4-b':5,6-b'']trithiophene-2,5,8-tricarbaldehyde serves as a versatile tri-functionalized building block for conjugated materials, enabling efficient construction of π-extended architectures via Wittig, Grignard, or reductive amination reactions. Its three aldehyde groups exhibit excellent bench stability and compatibility with diverse functional groups, facilitating modular synthesis of donor-acceptor systems for organic semiconductors and photovoltaic applications.
