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-Chloro-2-naphthol is a chlorinated naphthalene derivative featuring a reactive hydroxyl group at the 2-position and a chlorine substituent at the 1-position. This configuration imparts enhanced electrophilicity and stability under standard bench conditions, enabling efficient coupling in synthetic transformations. The molecule serves as a key intermediate in the preparation of dyes, pharmaceuticals, and functionalized polymers, particularly where halogenated aromatic scaffolds are required.

Application

1-Chloro-2-naphthol serves as a versatile building block in the synthesis of functionalized naphthalene derivatives and heterocyclic scaffolds. Its chloro group enables palladium-catalyzed cross-coupling reactions, while the phenolic hydroxyl facilitates derivatization via etherification or esterification. The compound exhibits good bench stability and is readily purified by recrystallization, making it well-suited for iterative synthetic sequences in medicinal chemistry and materials science applications.
