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

Ethyl 6-chloro-3-oxo-2,3-dihydropyridazine-4-carboxylate is a bench-stable heterocyclic building block featuring a chlorinated pyridazinone core. The electron-deficient ring system facilitates nucleophilic substitution and cycloaddition reactions. This compound integrates readily into medicinal chemistry scaffolds due to its compatibility with diverse functional groups and predictable reactivity under standard conditions.

Application

Ethyl 6-chloro-3-oxo-2,3-dihydropyridazine-4-carboxylate serves as a versatile building block in heterocyclic synthesis, enabling efficient access to substituted pyridazinones and related pharmacophores. The molecule features orthogonal functional groups—chlorine at C6, an enone system at C3–C4, and a pendant ester—enabling sequential transformations via nucleophilic substitution, condensation, or reduction. Its bench-stable nature and compatibility with standard reaction conditions facilitate reliable use in medicinal chemistry and process development workflows.
