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-Cyclopropyl-4H-1,2,4-triazol-3-amine features a cyclopropyl-substituted triazole core with enhanced solubility and stability under standard conditions. This electron-rich heterocycle serves as a key scaffold in medicinal chemistry, integrating readily into bioactive molecules through its nucleophilic amine functionality and favorable steric profile.

Application

5-Cyclopropyl-4H-1,2,4-triazol-3-amine serves as a versatile heterocyclic building block in medicinal chemistry, enabling the construction of triazolyl-containing scaffolds with enhanced metabolic stability. The cyclopropyl substituent provides steric and electronic modulation, while the primary amine functionality facilitates straightforward derivatization via amidation, alkylation, or coupling reactions. Its bench-stable nature and compatibility with standard synthetic protocols make it a practical choice for lead optimization and API intermediate development.
