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.

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+

Description

2,5-Dibromo-3,4-dinitrothiophene features a highly electron-deficient thiophene core stabilized by dual bromine and nitro substituents. This configuration enables robust coupling in transition-metal-catalyzed reactions, particularly in cross-coupling protocols requiring high reactivity. The molecule exhibits enhanced stability under standard handling conditions while maintaining strong electrophilic character at the ring positions.

Application

2,5-Dibromo-3,4-dinitrothiophene serves as a versatile building block for heterocyclic synthesis, enabling direct functionalization at the 2- and 5-positions via palladium-catalyzed cross-coupling reactions. The dinitro groups enhance electrophilicity at C-3 and C-4, facilitating nucleophilic substitution under mild conditions. Its bench-stable crystalline form supports straightforward handling and purification, making it well-suited for iterative synthesis of complex thiophene-based scaffolds in medicinal chemistry and materials science applications.
