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

3-Bromoimidazo[1,2-b]pyridazine is a brominated heterocyclic compound featuring a fused imidazo[1,2-b]pyridazine core. This electron-deficient scaffold enables direct functionalization in cross-coupling reactions. The bromine substituent provides a reactive handle for palladium-catalyzed transformations, facilitating rapid access to diverse analogs in medicinal chemistry and materials science applications.

Application

3-Bromoimidazo[1,2-b]pyridazine serves as a versatile building block for medicinal chemistry and heterocyclic synthesis, enabling palladium-catalyzed cross-coupling reactions with high functional group tolerance. Its bromine substituent facilitates efficient C–C and C–heteroatom bond formation under standard conditions, while the imidazo[1,2-b]pyridazine core provides a rigid, electron-deficient scaffold useful in kinase inhibitor and CNS-targeted compound development. The compound exhibits excellent bench stability and simplifies purification in multi-step syntheses.
