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

1-Bromo-3-chloronaphthalene is a dual-heteroatom-substituted naphthalene featuring regioselective bromine and chlorine positions. This configuration enables predictable coupling reactions in cross-coupling protocols, offering enhanced reactivity control. The molecule exhibits excellent stability under standard conditions and integrates readily into complex molecular architectures requiring precise halogen placement.

Application

1-Bromo-3-chloronaphthalene serves as a versatile bifunctional building block for cross-coupling and electrophilic substitution reactions. The bromo group enables efficient Pd-catalyzed coupling, while the chloro substituent offers orthogonal reactivity in selective transformations. Its bench-stable nature and compatibility with standard synthetic protocols make it ideal for constructing complex polycyclic architectures and functionalized heterocycles in medicinal chemistry and materials science applications.
