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

4-Amino-3-chlorobenzonitrile features a strategically positioned para-amino group and ortho-chloro substituent on a benzonitrile scaffold, enabling selective coupling reactions in pharmaceutical intermediates. This electron-rich aromatic system facilitates efficient transition metal-catalyzed transformations under standard conditions.

Application

4-Amino-3-chlorobenzonitrile serves as a versatile building block in medicinal chemistry, enabling direct functionalization at both the amino and nitrile positions. Its ortho-chloro substituent facilitates palladium-catalyzed cross-coupling reactions, while the amine group offers straightforward derivatization via acylation or reductive amination. The compound exhibits good bench stability and is readily purified by recrystallization, making it well-suited for multi-step synthesis of heterocyclic scaffolds and API intermediates.
