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-Acetylbenzaldehyde features a para-substituted benzaldehyde scaffold bearing both aldehyde and acetyl functional groups, enabling direct integration into condensation and coupling reactions. This electron-deficient aromatic system supports efficient derivatization in synthetic organic chemistry workflows under standard conditions.

Application

4-Acetylbenzaldehyde serves as a versatile building block in synthetic organic chemistry, enabling efficient access to conjugated enone systems and functionalized aromatic scaffolds. Its dual aldehyde and ketone functionalities offer orthogonal reactivity for sequential transformations, including aldol condensations, Wittig reactions, and nucleophilic additions. The compound exhibits good bench stability and is readily purified by recrystallization, facilitating integration into multi-step syntheses of pharmaceutical intermediates and specialty materials.
