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

4-Bromo-1H-pyrazolo[3,4-b]pyridine is a heterocyclic scaffold featuring a brominated pyrazolopyridine core, offering a versatile platform for transition metal-catalyzed coupling reactions. The electron-deficient aromatic system enables efficient functionalization, while the pendant bromine facilitates cross-coupling with minimal protection requirements. This compound serves as a key building block in medicinal chemistry and materials science applications.

Application

4-Bromo-1H-pyrazolo[3,4-b]pyridine serves as a versatile building block for heterocyclic synthesis, enabling palladium-catalyzed cross-coupling reactions with broad functional group tolerance. Its bromo substituent facilitates efficient C–C bond formation, while the fused pyrazolopyridine core provides structural rigidity and enhanced solubility. This compound functions reliably in late-stage diversification workflows and is compatible with standard purification methods, making it well-suited for medicinal chemistry and process development applications.
