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

Benzo[b]thiophen-2-amine delivers a fused heterocyclic scaffold with a reactive amine at the 2-position, enabling direct incorporation into pharmaceutical intermediates and functional materials. The electron-rich aromatic system enhances conjugation in donor-acceptor architectures, while the thiophene core supports stability under standard synthetic conditions. This compound serves as a key building block for optoelectronic materials and bioactive molecules.

Application

Benzo[b]thiophen-2-amine serves as a versatile heterocyclic building block in medicinal chemistry and materials science. Its electron-rich aromatic core and amine functionality enable direct coupling reactions, including Suzuki-Miyaura and Buchwald-Hartwig protocols. The molecule exhibits good bench stability, facilitates straightforward purification, and functions as a key scaffold for kinase inhibitors and organic semiconductors.
