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-Bromo-1-chloroisoquinoline is a halogenated isoquinoline scaffold featuring complementary reactivity at the 5-bromo and 1-chloro positions. This dual-halogenation pattern enables selective cross-coupling transformations in palladium-catalyzed reactions, facilitating efficient access to complex heterocyclic architectures. The molecule exhibits excellent stability under standard bench conditions and demonstrates favorable solubility in common organic solvents, supporting its utility in medicinal chemistry and materials synthesis workflows.

Application

5-Bromo-1-chloroisoquinoline serves as a versatile building block for transition-metal-catalyzed cross-coupling reactions, enabling the construction of substituted isoquinoline scaffolds under mild conditions. The orthogonal reactivity of bromo and chloro groups facilitates sequential functionalization, while the compound exhibits excellent bench stability and compatibility with standard purification methods. Its defined regiochemistry supports reliable synthesis of complex heterocycles relevant to medicinal chemistry and materials science.
