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-Bromo-4-(methylsulfonyl)pyridine features a bromine atom at the 2-position and a methylsulfonyl group at the 4-position on a pyridine ring, enabling selective cross-coupling reactions. The electron-deficient pyridine core enhances reactivity in palladium-catalyzed transformations, while the sulfonyl moiety improves solubility and stability under standard conditions.

Application

2-Bromo-4-(methylsulfonyl)pyridine serves as a versatile building block in medicinal chemistry, enabling palladium-catalyzed cross-coupling reactions due to its stable bromide and electron-withdrawing methylsulfonyl group. The pyridine core provides ortho-directing capability, while the sulfone moiety enhances solubility and metabolic stability. Its bench-stable nature facilitates straightforward handling and purification, making it well-suited for iterative synthesis of bioactive heterocycles and API intermediates.
