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.

Description

2-Bromo-5-iodothiophene is a halogenated thiophene derivative featuring complementary reactive sites for cross-coupling. The bromine and iodine substituents enable sequential functionalization under palladium catalysis, offering precise control in constructing complex heterocyclic architectures. This compound serves as a key building block in the synthesis of advanced materials and pharmaceutical intermediates.

Application

2-Bromo-5-iodothiophene serves as a versatile halogenated building block for cross-coupling reactions, enabling the construction of biaryl and heteroaryl scaffolds under palladium-catalyzed conditions. The complementary reactivity of bromo and iodo groups allows for sequential functionalization, while its bench-stable nature and compatibility with standard coupling protocols facilitate efficient synthesis of complex molecular architectures in medicinal chemistry and materials science applications.
