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-(2-Chloro-5-hydroxyphenyl)ethan-1-one features a chlorinated hydroxyaryl moiety linked to a ketone group, enabling direct functionalization in pharmaceutical intermediates. The ortho-chloro and para-hydroxy substituents create a polar, electron-deficient aromatic system ideal for coupling reactions. This compound exhibits bench-stable handling under standard conditions and integrates readily into complex molecular architectures requiring regioselective modifications.

Application

1-(2-Chloro-5-hydroxyphenyl)ethan-1-one serves as a versatile building block in medicinal chemistry, enabling direct functionalization at the phenolic hydroxyl group and facilitating electrophilic substitution at the aromatic ring. Its ketone functionality supports nucleophilic additions and condensation reactions, while the chloro and hydroxy substituents offer orthogonal handles for further derivatization. The compound exhibits good bench stability and is amenable to purification via recrystallization or chromatography, making it suitable for use in multi-step synthesis of bioactive heterocycles and API intermediates.
