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.

Type	HazMat Fee
Excepted Quantity	$0.00
FedEx Limited Quantities Ground	$0.00
Hazmat Ground shipping	$50.00+
Inaccessible (Haz class 6.1 or 9), Domestic	$68.00+
Accessible (Haz class 3, 4, 5 or 8), Domestic	$158.00+
Inaccessible (Haz class 6.1 or 9), International	$108.00+

Description

Pyridine-3,5-diol features two hydroxyl groups positioned at the 3- and 5-positions of the pyridine ring, creating a rigid, electron-rich scaffold. This configuration enhances solubility in polar solvents and supports strong hydrogen bonding, enabling its use as a directing group in transition metal catalysis. The molecule exhibits bench-stable behavior under standard conditions, facilitating integration into complex synthetic sequences without requiring inert atmosphere handling.

Application

Pyridine-3,5-diol serves as a versatile building block in medicinal chemistry and catalytic synthesis, enabling direct functionalization at both C3 and C5 positions due to its symmetric diol substitution. The molecule exhibits robust bench stability and facilitates efficient transition-metal-catalyzed cross-coupling reactions. Its dual hydroxyl groups provide orthogonal handles for derivatization, enhancing utility in the construction of heterocyclic scaffolds and bioactive molecules.
