Description

1-[2-Oxo-7-(4-Methyl-5-Ethyl-2H-1,2,3-Triazole-2-Yl)-2H-1-Benzopyran-3-Yl]-4-Methyl-1H-1,2,4-Triazole-4-Ium CAS NO 47456-03-1 is a high-purity, complex heterocyclic compound featuring a benzopyran core fused with two distinct triazole moieties. This unique molecular architecture makes it a valuable advanced intermediate for the synthesis of novel active pharmaceutical ingredients (APIs) and functional materials. It is primarily sought by pharmaceutical R&D and fine chemical synthesis teams developing next-generation therapeutic agents.

Application

• Pharmaceutical Intermediate: Key building block for the research and development of new drug candidates, particularly in oncology, antiviral, and anti-inflammatory therapeutic areas.
• Agrochemical Synthesis: Serves as a precursor for novel fungicides or herbicides, leveraging its heterocyclic structure for biological activity.
• Material Science Research: Used in the development of organic semiconductors, light-emitting materials, or metal-organic frameworks (MOFs) due to its conjugated system and coordination sites.
• Biochemical Probe Development: Potential scaffold for creating fluorescent tags or enzyme inhibitors for diagnostic and research applications.
• Academic & Contract Research: Supplied to universities and CROs for fundamental chemical research and method development in organic synthesis.

Quality Control

Our production of this advanced intermediate adheres to strict quality management protocols. Every batch is characterized and tested using advanced analytical techniques including HPLC, NMR, and mass spectrometry to ensure identity, purity, and consistency. A comprehensive Certificate of Analysis (COA) detailing purity, impurity profile, and analytical results is provided with each shipment to support your R&D and regulatory documentation needs.

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 exclude moisture. For long-term storage, consider using desiccants.
