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

6-Hydroxyquinolin-2(1H)-one features a fused bicyclic scaffold with a phenolic hydroxyl and lactam carbonyl, enabling dual hydrogen-bonding capacity. This structural motif enhances solubility and facilitates coordination in metal complexation, making it valuable for chelating agents and fluorescent probes. The compound exhibits bench-stable behavior under standard conditions.

Application

6-Hydroxyquinolin-2(1H)-one serves as a versatile scaffold in medicinal chemistry, enabling direct access to quinoline-based heterocycles through standard functionalization. Its dual hydroxyl and carbonyl groups provide sites for derivatization via esterification, etherification, or metal-catalyzed coupling reactions. The compound exhibits good bench stability and facilitates purification by recrystallization or column chromatography, making it suitable for iterative synthesis campaigns in API development and lead optimization.
