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

4-Iodo-2-methoxyphenol features a phenolic hydroxyl group flanked by an iodine atom at the para position and a methoxy substituent at the ortho position, enabling selective cross-coupling reactions. This electron-rich aryl iodide integrates readily into complex molecular architectures under standard conditions, offering enhanced reactivity and stability in synthetic workflows.

Application

4-Iodo-2-methoxyphenol serves as a versatile building block in the synthesis of functionalized aromatic scaffolds, enabling palladium-catalyzed cross-coupling reactions due to its iodide functionality. The ortho-methoxy group enhances regioselectivity and provides a handle for further derivatization. Its bench-stable nature and compatibility with standard reaction conditions make it well-suited for medicinal chemistry and materials applications.
