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

5-Bromo-4-methoxypicolinonitrile features a pyridine core functionalized with bromine, methoxy, and nitrile groups at positions 5, 4, and 3 respectively. This electron-deficient heterocycle integrates readily into cross-coupling reactions, enabling efficient construction of complex pharmaceutical intermediates under standard conditions.

Application

5-Bromo-4-methoxypicolinonitrile serves as a versatile building block for heterocyclic synthesis, enabling palladium-catalyzed cross-coupling reactions due to its dual electrophilic sites. The bromine and nitrile groups facilitate sequential functionalization, while the methoxy substituent enhances solubility and modulates reactivity. Its bench-stable nature and compatibility with standard reaction conditions make it well-suited for medicinal chemistry campaigns and API intermediate development.
