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-Ethoxy-2-hydroxybenzaldehyde features a hydroxyl group ortho to the aldehyde and an ethoxy substituent at the para position, creating a polar, electron-rich aromatic scaffold. This arrangement enhances solubility in protic solvents and supports facile derivatization in synthetic pathways. The molecule exhibits stability under standard bench conditions and serves as a key intermediate in the synthesis of bioactive heterocycles and functionalized aromatics.

Application

4-Ethoxy-2-hydroxybenzaldehyde serves as a versatile building block in synthetic organic chemistry, enabling access to substituted phenolic scaffolds via standard coupling and functional group transformation protocols. Its ortho-hydroxy and para-ethoxy substituents provide enhanced solubility and stability, while the aldehyde functionality facilitates efficient condensation reactions, reductive amination, and heterocycle formation under mild conditions. The compound exhibits robust bench stability and is compatible with common purification methods, making it suitable for medicinal chemistry campaigns and process development workflows.
