Description

Ethyl 7-Amino-2-(methylthio)[1,2,4]triazolo[1,5-a]pyrimidine-6-carboxylate is a high-purity, advanced pharmaceutical intermediate characterized by its fused triazolopyrimidine heterocyclic structure. This compound is a critical building block in the synthesis of novel active pharmaceutical ingredients (APIs), particularly those targeting complex biological pathways. It is essential for research and development chemists and manufacturers in the pharmaceutical and agrochemical sectors who require reliable, high-quality intermediates for scale-up and production.

Application

• Pharmaceutical Intermediate: A key precursor in the synthesis of triazolopyrimidine-based drug candidates, including potential kinase inhibitors and antiviral agents.
• Agrochemical Research: Used in the development of new herbicides and fungicides, leveraging its heterocyclic core for bioactivity.
• Chemical Synthesis Building Block: Serves as a versatile scaffold for medicinal chemistry and structure-activity relationship (SAR) studies due to its reactive amino and ester functional groups.
• Academic & Contract Research: Employed in university and CRO laboratories for exploratory research into novel heterocyclic compounds and their properties.

Quality Control

Our Ethyl 7-Amino-2-(Methylthio)[1,2,4]Triazolo[1,5-A]Pyrimidine-6-Carboxylate is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via IR and NMR spectroscopy, to ensure it meets the high standards required for pharmaceutical R&D and production. A comprehensive Certificate of Analysis (COA) detailing all specifications and test results is provided with each shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to prevent moisture absorption, which may affect stability and performance.
