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

Pyridine-3,5-diamine features two amino groups positioned at the 3- and 5-positions of a pyridine ring, creating a rigid, electron-rich scaffold. This arrangement enables strong coordination to transition metals and facilitates integration into conjugated systems. The compound exhibits enhanced solubility in polar solvents and stability under standard bench conditions, making it valuable for ligand design and functional material synthesis.

Application

Pyridine-3,5-diamine serves as a versatile building block in medicinal chemistry and catalysis, enabling the synthesis of heterocyclic scaffolds through standard coupling reactions. Its ortho-diamino configuration provides excellent functional group tolerance and facilitates metal coordination in transition-metal-catalyzed transformations. The compound exhibits good bench stability and is readily purified by recrystallization, making it well-suited for scalable synthetic workflows.
