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+

Description

2-Chloro-4-iodo-5-methoxypyridine features a pyridine core functionalized with chlorine, iodine, and methoxy groups at distinct positions, enabling selective cross-coupling reactions. The electron-deficient aromatic ring pairs with the reactive iodide for efficient Pd-catalyzed transformations. This scaffold offers high stability under standard conditions and facilitates rapid diversification in medicinal chemistry and agrochemical development.

Application

2-Chloro-4-iodo-5-methoxypyridine serves as a versatile building block in cross-coupling chemistry, enabling the efficient construction of substituted pyridine scaffolds. The orthogonal reactivity of chlorine and iodine facilitates sequential functionalization, while the methoxy group offers mild directing effects and compatibility with standard reaction conditions. Its bench-stable nature and predictable coupling behavior make it well-suited for medicinal chemistry and process development workflows.
