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-3-iodopyridin-2(1H)-one features a dual-halogenated pyridinone core enabling precise cross-coupling transformations. The bromine and iodine substituents offer orthogonal reactivity, facilitating sequential functionalization in complex molecule assembly. This bench-stable scaffold integrates readily into diverse heterocyclic architectures under standard conditions.

Application

5-Bromo-3-iodopyridin-2(1H)-one serves as a versatile dihalogenated pyridinone building block for cross-coupling reactions, enabling efficient access to substituted heterocycles. The bromo and iodo groups exhibit complementary reactivity in palladium-catalyzed coupling protocols, allowing sequential functionalization with high chemoselectivity. Bench-stable and compatible with standard purification methods, it facilitates the synthesis of complex scaffolds in medicinal chemistry and materials science applications.
