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

5,7-Dichloro-1H-[1,2,3]triazolo[4,5-b]pyridine is a heterocyclic scaffold featuring two electron-withdrawing chlorine substituents at the 5 and 7 positions. This configuration enhances electrophilicity at the triazolopyridine core, enabling efficient coupling reactions in medicinal chemistry. The molecule exhibits robust stability under standard bench conditions and integrates readily into complex molecular architectures.

Application

5,7-Dichloro-1H-[1,2,3]triazolo[4,5-b]pyridine serves as a versatile heterocyclic building block for medicinal chemistry and materials science. Its electron-deficient triazolopyridine core enables efficient coupling reactions with nucleophiles, facilitating the construction of complex scaffolds. The dichloro substitution pattern provides orthogonal reactivity for sequential functionalization, while the compound exhibits excellent bench stability and compatibility with standard purification techniques.
