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

Thieno[3,2-b]thiophene-2-carbaldehyde features a fused heterocyclic core with a reactive aldehyde group at the 2-position. This electron-deficient scaffold integrates readily into conjugated systems, enabling efficient coupling in synthetic routes for organic semiconductors and functional materials. The aldehyde moiety offers direct access to imine derivatives and facilitates further functionalization under mild conditions.

Application

Thieno[3,2-b]thiophene-2-carbaldehyde serves as a versatile building block in the synthesis of conjugated materials and heterocyclic scaffolds. Its aldehyde functionality enables efficient coupling reactions, including Wittig, Horner–Wadman, and reductive amination, facilitating access to functionalized derivatives. The fused thiophene core provides enhanced planarity and electron-rich character, supporting applications in organic semiconductors and photovoltaic materials. Bench-stable and compatible with standard purification methods, it functions reliably in multi-step synthetic sequences.
