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

7-Bromo-5-chloro-1H-pyrazolo[4,3-b]pyridine features a fused bicyclic core with strategically positioned halogens enabling direct functionalization in cross-coupling reactions. The electron-deficient pyridine ring facilitates nucleophilic substitution, while the bromo and chloro substituents offer orthogonal reactivity for sequential derivatization. This scaffold integrates readily into complex heterocycles used in medicinal chemistry and materials science.

Application

7-Bromo-5-chloro-1H-pyrazolo[4,3-b]pyridine serves as a versatile heterocyclic building block for the synthesis of bioactive compounds, enabling palladium-catalyzed cross-coupling reactions due to its well-defined halogen positions. The bromo and chloro substituents offer orthogonal reactivity, facilitating sequential functionalization in medicinal chemistry and materials science applications. Its bench-stable nature and compatibility with standard coupling protocols make it ideal for modular scaffold construction in API development and chemical library synthesis.
