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

7-Chloro-3,4-dihydronaphthalen-1(2H)-one is a chlorinated dihydronaphthalenone scaffold featuring a labile enolizable carbonyl and electron-deficient aromatic ring. This structure integrates readily into synthetic routes requiring π-electron modulation, offering enhanced reactivity in electrophilic substitution and transition-metal-catalyzed coupling processes under standard conditions.

Application

7-Chloro-3,4-dihydronaphthalen-1(2H)-one serves as a versatile building block in medicinal chemistry, enabling the synthesis of bioactive heterocycles and drug-like scaffolds. Its fused bicyclic structure provides defined stereochemistry and enhanced metabolic stability, while the ketone functionality facilitates nucleophilic additions and enolate chemistry. Bench-stable and compatible with standard functional group transformations, it functions effectively in multistep syntheses for API development.
