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

4-Amino-6-chloropyridazin-3(2H)-one features a fused heterocyclic core with complementary electron-rich and electrophilic sites, enabling direct functionalization in medicinal chemistry. The amino group facilitates coupling reactions, while the chloro substituent serves as a regioselective handle for nucleophilic substitution under mild conditions. This scaffold exhibits favorable solubility and stability under standard bench protocols, making it a practical building block for targeted library synthesis.

Application

4-Amino-6-chloropyridazin-3(2H)-one serves as a versatile building block in medicinal chemistry, enabling efficient access to substituted pyridazinones via nucleophilic displacement or cross-coupling. The chloro group facilitates direct functionalization under mild conditions, while the amino and carbonyl functionalities provide orthogonal handles for further derivatization. Bench-stable and readily purified by recrystallization, it functions effectively in standard synthetic workflows for heterocyclic scaffold development.
