Description

5-Ethylthio-1H-Tetrazole is a versatile heterocyclic organic compound primarily utilized as a key building block and reagent in specialized chemical synthesis. Its unique structure makes it valuable for introducing the tetrazole moiety, a bioisostere for carboxylic acids, into target molecules. This compound is particularly relevant for researchers and manufacturers in the pharmaceutical, agrochemical, and material science sectors, where it serves as a critical intermediate in the development of active ingredients and functional materials.

Application

• Pharmaceutical Intermediate: A crucial building block in the synthesis of active pharmaceutical ingredients (APIs), especially those containing tetrazole rings, such as certain sartans (angiotensin II receptor blockers).
• Agrochemical Synthesis: Used in the research and production of herbicides, fungicides, and insecticides where the tetrazole group imparts specific biological activity.
• Material Science & Polymer Chemistry: Acts as a monomer or cross-linking agent in the development of specialty polymers, including polyurethanes and other high-performance materials.
• Coordination Chemistry & Ligand Synthesis: Serves as a precursor for creating nitrogen-donor ligands used in catalysis and metal-organic frameworks (MOFs).
• Energetic Materials Research: Investigated as a component in the formulation of propellants and explosives due to the high nitrogen content of the tetrazole ring.
• Peptide Chemistry & Bioconjugation: Employed in peptide synthesis and bioconjugation techniques as a coupling reagent or for introducing specific functional handles.

Quality Control

Our 5-Ethylthio-1H-Tetrazole is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure high purity and consistency, meeting the stringent requirements for advanced chemical synthesis. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment to guarantee traceability and support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed to prevent degradation from atmospheric moisture. Keep away from incompatible materials.
