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-4-methoxynicotinonitrile features a strategically positioned nitrile group and chloro substituent on a pyridine scaffold, enabling direct integration into heterocyclic scaffolds. The methoxy functionality enhances solubility and modulates electronic properties, supporting efficient coupling in synthetic sequences under standard conditions.

Application

2-Chloro-4-methoxynicotinonitrile serves as a versatile building block in medicinal chemistry, enabling efficient access to substituted pyridine scaffolds via nucleophilic displacement and cross-coupling reactions. The ortho-chloro group facilitates regioselective functionalization, while the nitrile and methoxy substituents offer complementary reactivity for downstream transformations. Its bench stability and compatibility with standard reaction conditions make it ideal for modular synthesis of bioactive heterocycles and API intermediates.
