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-Chloroisoquinoline is a bench-stable heterocyclic scaffold featuring a chlorine substituent at the 4-position, enhancing electrophilicity for directed functionalization. This electron-deficient core integrates readily into pharmaceutical intermediates and materials chemistry, enabling efficient coupling reactions under standard conditions.

Application

4-Chloroisoquinoline serves as a versatile building block in medicinal chemistry and heterocyclic synthesis, enabling palladium-catalyzed cross-coupling reactions such as Suzuki, Stille, and Negishi couplings. Its electrophilic chlorine atom facilitates efficient functionalization at the C4 position while maintaining stability under standard reaction conditions. The scaffold is compatible with diverse protecting groups and supports modular assembly of complex isoquinoline-based architectures relevant to pharmaceutical development.
