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

3-Bromo-4-chloro-1H-pyrazolo[3,4-b]pyridine features a fused bicyclic core with complementary halogen substituents enabling diverse cross-coupling transformations. The bromine and chlorine atoms facilitate selective functionalization in palladium-catalyzed reactions, while the electron-deficient pyridine ring enhances reactivity in nucleophilic substitution processes. This scaffold delivers access to complex heterocyclic architectures under standard conditions.

Application

3-Bromo-4-chloro-1H-pyrazolo[3,4-b]pyridine serves as a versatile heterocyclic building block for medicinal chemistry and materials science. Its dual halogenation enables efficient Pd-catalyzed cross-coupling reactions, including Suzuki-Miyaura and Buchwald-Hartwig aminations, with excellent functional group tolerance. The molecule exhibits robust bench stability and facilitates the construction of complex polycyclic scaffolds commonly found in kinase inhibitors and bioactive small molecules.
