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

4-Bromo-2-ethoxypyridine is a bench-stable pyridine derivative featuring a bromine atom at the C4 position and an ethoxy group at C2, enabling selective cross-coupling reactions. The electron-deficient aromatic core pairs effectively with palladium catalysts, delivering high yields in Suzuki-Miyaura and Negishi transformations under standard conditions.

Application

4-Bromo-2-ethoxypyridine serves as a versatile building block in medicinal chemistry and cross-coupling synthesis, enabling efficient access to substituted pyridines via Pd-catalyzed reactions. The ethoxy group enhances solubility and provides a handle for further derivatization, while the bromine site offers high reactivity in Suzuki, Stille, and Negishi couplings. Bench-stable and readily purified by column chromatography, it functions reliably in multi-step syntheses of pharmaceutical intermediates and functional materials.
