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-Chloro-5-methoxypyridine is a bench-stable heterocyclic building block featuring a chlorine atom at the 2-position and a methoxy group at the 5-position of the pyridine ring. This electronic configuration enables selective cross-coupling reactions and facilitates downstream derivatization in medicinal chemistry and agrochemical synthesis.

Application

2-Chloro-5-methoxypyridine serves as a versatile building block in synthetic organic chemistry, enabling palladium-catalyzed cross-coupling reactions due to its well-defined electrophilic site at the 2-position. The methoxy group at C5 provides moderate electron donation and enhances solubility, while the chloropyridine core offers excellent stability under standard reaction conditions. Its compatibility with diverse nucleophiles facilitates the construction of complex heterocyclic scaffolds relevant to agrochemical and medicinal chemistry applications.
