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

2,5-Pyridine dicarboxaldehyde features two aldehyde groups positioned at the 2- and 5-positions of a pyridine ring, creating a rigid, electron-deficient heteroaromatic scaffold. This geometry enables selective coordination in transition metal catalysis and facilitates integration into porous materials. The molecule exhibits enhanced stability under standard conditions and displays favorable solubility in common organic solvents, supporting its use in synthetic transformations and molecular design.

Application

2,5-Pyridine dicarboxaldehyde serves as a versatile bifunctional building block in synthetic organic chemistry, enabling efficient construction of heterocyclic scaffolds and molecular architectures. Its orthogonal aldehyde functionality facilitates selective derivatization, while the pyridine core provides enhanced solubility and stability under standard reaction conditions. The compound functions effectively in reductive amination, Schiff base formation, and transition-metal-catalyzed coupling processes, offering reliable performance in medicinal chemistry and materials synthesis workflows.
