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-Chloro-2,3-dimethyl-1H-indole is a halogenated indole derivative featuring a chloro substituent at the 5-position and methyl groups at the 2- and 3-positions. This electron-deficient scaffold integrates readily into bioactive molecule design, offering enhanced metabolic stability and favorable lipophilic character for medicinal chemistry applications.

Application

5-Chloro-2,3-dimethyl-1H-indole serves as a versatile building block in medicinal chemistry, enabling efficient access to substituted indole scaffolds via standard coupling reactions. Its defined substitution pattern offers predictable reactivity in Pd-catalyzed cross-couplings and electrophilic functionalization, while the methyl groups enhance metabolic stability and modulate lipophilicity. Bench-stable and readily purified by column chromatography, it facilitates reproducible synthesis of complex heterocycles and API intermediates.
