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-Bromo-5-chloronaphthalen-2-ol features a naphthalene core bearing bromo and chloro substituents at the 4- and 5-positions, respectively, with a hydroxyl group at the 2-position. This electron-deficient scaffold enables direct coupling in cross-coupling reactions and serves as a building block for bioactive molecules and functional materials.

Application

4-Bromo-5-chloronaphthalen-2-ol serves as a versatile building block for the synthesis of functionalized naphthalene scaffolds. Its ortho-hydroxyl group enables direct coupling in Suzuki-Miyaura and Ullmann reactions, while the bromo and chloro substituents offer complementary reactivity for sequential cross-coupling. The molecule exhibits good bench stability and facilitates straightforward purification, making it well-suited for iterative synthetic strategies in medicinal chemistry and materials science applications.
