Description

Zinc 3,5-Heptanedionate CAS NO 21499-03-6 is a coordination compound where zinc is chelated by two 3,5-heptanedionate ligands. This compound serves as a versatile and thermally stable precursor for the synthesis of zinc oxide (ZnO) nanomaterials and thin films. It is primarily utilized by manufacturers and R&D laboratories in advanced material science, electronics, and catalysis. Its utility stems from its volatility and clean decomposition profile, making it ideal for chemical vapor deposition (CVD) and sol-gel processes.

Application

• Precursor for Zinc Oxide (ZnO) Nanomaterials: Used in chemical vapor deposition (CVD), atomic layer deposition (ALD), and sol-gel synthesis to produce high-purity ZnO nanoparticles, nanowires, and thin films for optoelectronic devices.
• Catalyst and Catalyst Support: Acts as a catalyst or a precursor for catalysts in organic synthesis and polymerization reactions.
• Cross-linking Agent: Employed in polymer chemistry to modify resin properties and enhance thermal stability.
• Additive in Functional Coatings: Incorporated into coatings to impart UV-blocking, antimicrobial, or corrosion-resistant properties.
• Research & Development: Serves as a standard or starting material in academic and industrial research for developing new materials and chemical processes.
• Dopant Source: Used as a source of zinc ions for doping other metal oxide matrices to tune their electrical or optical characteristics.

Quality Control

Our Zinc 3,5-Heptanedionate is manufactured under strict quality management protocols. Each batch undergoes rigorous analytical testing to ensure high purity and consistency, meeting the stringent requirements for advanced material synthesis. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are provided with every shipment and are available upon request.

Storage

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