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

5-Amino-2-chlorobenzothiazole features a reactive amino group flanked by a chlorine substituent on a benzothiazole core, enabling direct coupling in cross-coupling reactions. This electron-rich heterocycle exhibits enhanced solubility in polar solvents and stability under standard bench conditions, facilitating its use in synthesizing bioactive compounds and functional materials.

Application

5-Amino-2-chlorobenzothiazole serves as a versatile building block in medicinal chemistry, enabling direct functionalization at the amino and chloro positions. Its ortho-chloro group facilitates palladium-catalyzed cross-coupling reactions, while the primary amine supports derivatization via acylation, alkylation, or condensation. The benzothiazole core provides metabolic stability and enhanced binding affinity in bioactive scaffolds. Bench-stable and readily purified by recrystallization, it functions efficiently in multi-step syntheses of kinase inhibitors and antitumor agents.
