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

2,4-Dibromoquinoline is a brominated quinoline derivative featuring two bromine atoms at the 2- and 4-positions, conferring enhanced electrophilicity and stability. This configuration enables direct use in palladium-catalyzed cross-coupling reactions, where it integrates efficiently into complex molecular architectures. The compound exhibits excellent bench-stability and compatibility with standard synthetic protocols.

Application

2,4-Dibromoquinoline serves as a versatile building block in transition-metal-catalyzed cross-coupling reactions, enabling efficient construction of biaryl and heteroaryl architectures. The bromine substituents at the 2- and 4-positions exhibit high reactivity under palladium-catalyzed conditions, facilitating Suzuki, Stille, and Negishi couplings with excellent functional group tolerance. Its bench-stable crystalline form simplifies handling and purification, making it well-suited for iterative synthesis in medicinal chemistry and materials science applications.
