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

2,4-Dihydroxypyridine features a pyridine core bearing two hydroxyl groups at the 2- and 4-positions, enabling strong hydrogen bonding and enhanced solubility. This arrangement imparts unique reactivity in nucleophilic substitution and transition metal-catalyzed coupling processes. The molecule exhibits bench-stable behavior under standard conditions and serves as a key scaffold in medicinal chemistry for bioactive heterocycle synthesis.

Application

2,4-Dihydroxypyridine serves as a versatile building block in medicinal chemistry, enabling efficient construction of heterocyclic scaffolds through electrophilic substitution and transition-metal-catalyzed coupling reactions. Its dual hydroxyl groups provide orthogonal reactivity for selective derivatization, while the pyridine core offers favorable electronic properties for drug-like molecule design. The compound exhibits good bench stability and is readily purified by recrystallization, facilitating integration into multi-step synthetic sequences.
