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+

Description

Thiophene-3,4-diamine dihydrochloride delivers a highly reactive, bench-stable scaffold for conjugate addition and transition-metal-catalyzed coupling. The diamine moiety, flanked by electron-rich thiophene rings, enables efficient integration into functionalized heterocycles. This form ensures enhanced solubility in polar media and simplified handling under standard conditions.

Application

Thiophene-3,4-diamine dihydrochloride serves as a versatile building block for the synthesis of functionalized heterocycles and bioactive scaffolds. Its dual amine functionality enables straightforward conjugation in amide couplings, reductive amination, and transition-metal-catalyzed cross-coupling reactions. The dihydrochloride salt form enhances solubility and bench stability, facilitating handling and purification in synthetic workflows. Widely employed in medicinal chemistry and materials science, it functions as a key intermediate for constructing thiophene-based pharmaceuticals and conductive polymers.
