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-Chloro-1H-indole-3-carbaldehyde features a chlorinated indole core with a reactive aldehyde group at the 3-position, enabling direct coupling in C–C bond formation. This electron-deficient scaffold integrates readily into bioactive molecule design, particularly in medicinal chemistry and heterocyclic synthesis workflows.

Application

2-Chloro-1H-indole-3-carbaldehyde serves as a versatile building block in medicinal chemistry and heterocyclic synthesis, enabling efficient access to indole-based scaffolds. The aldehyde functionality facilitates reductive amination, Grignard additions, and Ugi-type reactions, while the 2-chloro substituent offers orthogonal reactivity for subsequent functionalization. Its bench-stable nature and compatibility with standard purification methods make it well-suited for iterative synthesis workflows in API development and library generation.
