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+
Accessible (Haz class 3, 4, 5 or 8), Domestic	$158.00+

Description

6-Bromopyrrolo[1,2-b]pyridazin-4-ol features a brominated heterocyclic core with a phenolic hydroxyl group, enabling direct functionalization in cross-coupling and bioconjugation workflows. The electron-deficient pyridazine ring facilitates nucleophilic substitution, while the bench-stable scaffold supports integration into pharmaceutical intermediates and advanced materials under standard conditions.

Application

6-Bromopyrrolo[1,2-b]pyridazin-4-ol serves as a versatile building block in medicinal chemistry, enabling direct functionalization via palladium-catalyzed cross-coupling reactions. The bromine and hydroxyl groups offer orthogonal reactivity, facilitating sequential derivatization. Its stability under standard synthetic conditions and compatibility with diverse coupling partners make it ideal for constructing complex heterocyclic scaffolds relevant to kinase inhibitor and CNS-targeted drug discovery.
