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

Methyl 6-chloro-4-methylpyridazine-3-carboxylate features a sterically hindered pyridazine core with complementary electron-withdrawing and donating substituents, enabling efficient coupling in late-stage functionalization. The methyl ester group facilitates direct derivatization under standard conditions, while the chlorine atom serves as a reliable handle for nucleophilic substitution. This compound exhibits excellent bench stability and solubility in common organic solvents, streamlining its integration into synthetic workflows.

Application

Methyl 6-chloro-4-methylpyridazine-3-carboxylate serves as a versatile building block for heterocyclic synthesis, enabling palladium-catalyzed cross-coupling reactions and nucleophilic substitution at the C6 chlorine site. The methyl and ester functionalities offer orthogonal reactivity, facilitating further derivatization in medicinal chemistry and process development. Bench-stable and readily purified by column chromatography, it functions efficiently in standard synthetic workflows.
