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-Bromo-7-methoxynaphthalene features a bromine atom at the 2-position and a methoxy group at the 7-position on a naphthalene core. This substitution pattern imparts enhanced stability and tailored reactivity, enabling efficient coupling in palladium-catalyzed transformations. The electron-donating methoxy group modulates electronic density, while the bromide serves as a reliable handle for cross-coupling reactions.

Application

2-Bromo-7-methoxynaphthalene serves as a versatile building block in transition-metal-catalyzed cross-coupling reactions, enabling efficient construction of biaryl scaffolds. The bromine at the 2-position provides high reactivity in palladium-catalyzed couplings, while the 7-methoxy group offers moderate electron-donating character and enhanced solubility. Its bench-stable nature and compatibility with diverse functional groups facilitate straightforward purification and integration into complex molecular architectures.
