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

3,6-Dichloropyridazin-4-amine is a bench-stable heterocyclic amine featuring two chlorine substituents at the 3 and 6 positions of the pyridazine core. This electron-deficient scaffold enables direct functionalization in cross-coupling reactions and serves as a key building block in medicinal chemistry for kinase inhibitors and agrochemicals.

Application

3,6-Dichloropyridazin-4-amine serves as a versatile building block in medicinal chemistry, enabling the construction of bioactive heterocycles through nucleophilic substitution and cross-coupling reactions. Its dual chlorine substituents provide orthogonal reactivity for sequential functionalization, while the pyridazinamine core offers excellent stability and compatibility with common reaction conditions. The compound facilitates efficient access to substituted pyridazines used in agrochemicals and pharmaceutical scaffolds.
