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-Chloro-2-hydroxybenzaldehyde features a hydroxyl group ortho to the aldehyde, enabling intramolecular hydrogen bonding that enhances stability and influences reactivity. This electron-deficient aromatic scaffold integrates readily into synthetic pathways for bioactive molecules, particularly in pharmaceutical intermediates and ligand design.

Application

4-Chloro-2-hydroxybenzaldehyde serves as a versatile building block in synthetic organic chemistry, enabling efficient construction of bioactive heterocycles and pharmaceutical intermediates. Its ortho-hydroxyl group facilitates intramolecular cyclization, while the aldehyde functionality supports nucleophilic addition and condensation reactions. The electron-withdrawing chlorine substituent enhances reactivity in electrophilic substitution and improves metabolic stability in downstream drug candidates. This compound exhibits excellent bench stability and is readily purified by recrystallization, making it well-suited for routine laboratory-scale synthesis and process development.
