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.

Type	HazMat Fee
Excepted Quantity	$0.00
FedEx Limited Quantities Ground	$0.00
Hazmat Ground shipping	$50.00+
Inaccessible (Haz class 6.1 or 9), Domestic	$68.00+

Description

6-Bromo-2,3-dihydrophthalazine-1,4-dione features a brominated phthalazine core with two carbonyl groups, offering enhanced reactivity for cross-coupling and functionalization. The electron-deficient ring system facilitates nucleophilic substitution, while the bench-stable nature enables straightforward handling in synthetic workflows. This scaffold integrates readily into bioactive molecules and advanced materials.

Application

6-Bromo-2,3-dihydrophthalazine-1,4-dione serves as a versatile building block in medicinal chemistry, enabling late-stage functionalization via palladium-catalyzed cross-coupling reactions. Its bromine substituent facilitates efficient C–C bond formation while the dihydrophthalazine-1,4-dione core provides excellent stability and solubility for bench-scale synthesis. Functions reliably in Suzuki, Stille, and Negishi coupling protocols, offering predictable reactivity and straightforward purification.
