    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

Perchloropyridazine features a highly electron-deficient pyridazine core substituted with four chlorine atoms, enhancing its reactivity in electrophilic transformations. This robust scaffold serves as a valuable building block in the synthesis of advanced pharmaceutical intermediates and functional materials, offering enhanced stability under standard conditions.

Application

Perchloropyridazine serves as a versatile building block in synthetic organic chemistry, enabling the construction of nitrogen-rich heterocyclic scaffolds. Its high electrophilicity at the pyridazine core facilitates nucleophilic substitution reactions under mild conditions, offering efficient access to functionalized derivatives. The compound exhibits excellent bench stability and compatibility with diverse functional groups, making it valuable for medicinal chemistry campaigns and process-scale synthesis.
