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-Pyridin-4-yl-benzaldehyde features a conjugated bipyridyl-aldehyde architecture that enables efficient integration into cross-coupling and condensation reactions. The aldehyde group provides a reactive handle for nucleophilic addition, while the para-substituted pyridine ring enhances solubility and electronic modulation in transition metal catalysis. This compound serves as a key building block for functionalized heterocycles and advanced ligand systems.

Application

4-Pyridin-4-yl-benzaldehyde serves as a versatile bifunctional building block in synthetic organic chemistry, enabling efficient construction of conjugated systems and heterocyclic scaffolds. Its dual aromatic functionality—pyridine and benzene rings flanking an aldehyde group—facilitates reliable coupling reactions, including Suzuki-Miyaura cross-couplings and reductive aminations. The aldehyde moiety exhibits excellent stability under standard bench conditions and tolerates a range of functional groups, supporting straightforward purification and integration into complex molecular architectures.
