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-(Diethoxymethyl)benzaldehyde was used in the synthesis of 4-(diethoxymethyl)benzyl alcohol.

Application

Terephthaldehyde monodiethylacetal serves as a stable, bench-ready synthon for aromatic dialdehyde derivatives, enabling controlled introduction of aldehyde functionality in multi-step synthesis. Its diethylacetal protection enhances handling and purification while allowing selective deprotection under mild acidic conditions. The compound functions effectively in coupling reactions, heterocycle formation, and polymer building blocks, offering predictable reactivity and compatibility with diverse functional groups.
