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

6-Bromo-1-chlorophthalazine delivers a dual halogenation pattern ideal for cross-coupling transformations. This electron-deficient heterocycle integrates readily into pharmaceutical scaffolds, offering enhanced reactivity in palladium-catalyzed processes under standard conditions.

Application

6-Bromo-1-chlorophthalazine serves as a versatile building block in heterocyclic synthesis, enabling palladium-catalyzed cross-coupling reactions at both the bromo and chloro positions. Its dual electrophilic sites facilitate sequential functionalization, while the phthalazine core provides inherent stability and compatibility with diverse reaction conditions. The compound exhibits excellent bench stability and simplifies purification, making it well-suited for iterative synthesis of complex pharmaceutical scaffolds and kinase inhibitors.
