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

Description

2-Chloro-5-hydroxypyridine features a hydroxyl group positioned ortho to the chlorine substituent on a pyridine core, enabling direct functionalization at the C5 position. This arrangement facilitates nucleophilic substitution and coupling reactions under mild conditions, making it valuable for synthesizing bioactive heterocycles and advanced intermediates in medicinal chemistry.

Application

2-Chloro-5-hydroxypyridine serves as a versatile building block in heterocyclic synthesis, enabling regioselective functionalization at the pyridine ring. The hydroxyl group facilitates direct coupling reactions or conversion to more reactive electrophiles, while the chlorine atom provides a reliable handle for palladium-catalyzed cross-coupling processes. Its bench-stable nature and compatibility with common protecting group strategies make it well-suited for iterative synthesis workflows in medicinal chemistry and process development.
