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-7-methyl-1H-indole is a substituted indole featuring a chlorine atom at the 5-position and a methyl group at the 7-position, conferring enhanced electron-withdrawing character and steric bulk. This scaffold integrates readily into bioactive molecules, particularly in medicinal chemistry applications where modulated lipophilicity and metabolic stability are critical.

Application

5-Chloro-7-methyl-1H-indole serves as a valuable building block in medicinal chemistry, enabling the synthesis of substituted indole scaffolds via palladium-catalyzed cross-coupling reactions. Its ortho-chloro functionality provides a reliable handle for C–H activation and Suzuki-Miyaura coupling, while the methyl group enhances metabolic stability and modulates electronic properties. The compound exhibits excellent bench stability, facilitating handling and purification in standard laboratory workflows.
