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

2,5-Dibromothiophene-3-carboxylic acid features a rigid thiophene core bearing bromine substituents at the 2 and 5 positions and a carboxylic acid group at the 3 position. This arrangement enables direct functionalization in cross-coupling reactions, offering high reactivity under palladium catalysis. The molecule exhibits excellent stability under standard conditions, facilitating straightforward integration into complex molecular architectures for materials science and pharmaceutical applications.

Application

2,5-Dibromothiophene-3-carboxylic acid serves as a versatile building block for the synthesis of functionalized thiophene-based scaffolds in medicinal chemistry and materials science. The carboxylic acid group enables direct derivatization via amide coupling or esterification, while the dibromo substitution pattern facilitates palladium-catalyzed cross-coupling reactions such as Suzuki-Miyaura and Stille couplings. Its bench-stable crystalline form and orthogonal reactivity support efficient multistep synthesis with high functional group tolerance.
