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 3-amino-6-chloropyridazine-4-carboxylate features a pyridazine core functionalized with amino, chloro, and ester groups, enabling diverse synthetic transformations. The electron-deficient heterocycle facilitates nucleophilic substitution, while the amino group offers direct coupling potential. This bench-stable reagent integrates efficiently into medicinal chemistry workflows for accessing nitrogen-rich scaffolds.

Application

Ethyl 3-amino-6-chloropyridazine-4-carboxylate serves as a versatile building block in heterocyclic synthesis, enabling efficient construction of pyridazine-based scaffolds. The amino and chloro groups offer orthogonal reactivity for nucleophilic substitution and amidation, while the ester functionality supports further derivatization. Its bench-stable nature and compatibility with standard coupling conditions facilitate reliable use in medicinal chemistry and process development workflows.
