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

6-Chloro-3-methyl[1,2,4]triazolo[4,3-b]pyridazine features a fused triazolopyridazine core with strategic chlorine and methyl substituents, enabling direct integration into bioactive molecule scaffolds. The electron-deficient heterocycle facilitates coupling reactions under mild conditions, while the chloro group serves as a versatile handle for nucleophilic substitution. This compound exhibits bench-stable handling and compatibility with diverse synthetic transformations.

Application

6-Chloro-3-methyl[1,2,4]triazolo[4,3-b]pyridazine serves as a versatile heterocyclic building block in medicinal chemistry, enabling direct functionalization at the C6 chloride site via palladium-catalyzed cross-coupling. Its methyl group at C3 provides regiochemical control and enhances metabolic stability. The triazolopyridazine core exhibits excellent bench stability, facilitating straightforward purification and integration into complex scaffolds. This compound functions effectively in standard SNAr and transition-metal-mediated transformations, making it valuable for rapid library synthesis and API development.
