What Is Zinc Acetate Dihydrate?

Zinc acetate dihydrate (Zn(CH₃COO)₂·2H₂O, CAS 5970-45-6) is the dihydrated form of zinc acetate, a white crystalline solid that is freely soluble in water. It is one of the most commonly used water-soluble zinc salts in laboratory settings, prized for its ease of handling, good solubility, and reliable purity. The compound releases zinc(II) ions in aqueous solution, making it a convenient source of Zn²⁺ for biochemical, chemical, and materials science research.

Aladdin Scientific supplies zinc acetate dihydrate under SKU Z433040, manufactured under GMP-compliant conditions at our Fengxian Phase II facility, ensuring batch-to-batch consistency for demanding research applications.

Purity, Grade, and Specifications

Zinc acetate dihydrate is available in multiple purity grades to suit different experimental needs:

• ACS/Analytical Reagent (AR) grade: Meets stringent purity standards suitable for quantitative analytical work and most biochemical assays.
• Laboratory/Technical grade: Appropriate for general preparative chemistry where ultrahigh purity is not critical.

Aladdin Scientific's Z433040 is produced under GMP-compliant manufacturing (Sigma number reference: 1.088), providing consistent quality documentation including Certificate of Analysis (CoA) with lot-specific purity data. Researchers should consult the CoA for each lot to confirm suitability for their specific application, particularly for cell culture or sensitive enzymatic assays.

Common Laboratory Applications

Zinc acetate dihydrate serves a broad range of research and industrial purposes:

• Biochemistry & Cell Biology: Used to supply Zn²⁺ ions in enzyme activity studies, protein crystallization, and as a cofactor supplement in cell culture media.
• Analytical Chemistry: Employed as a precipitating agent for proteins and nucleic acids, and in preparation of standard zinc solutions for AAS or ICP-MS calibration.
• Materials Science & Nanotechnology: Serves as a precursor for synthesis of zinc oxide (ZnO) nanoparticles, thin films, and semiconductor materials via sol-gel, hydrothermal, or chemical bath deposition methods.
• Polymer & Coating Chemistry: Acts as a cross-linking agent and catalyst in certain polymer systems.
• Pharmaceutical Research: Used in studies of zinc-dependent biological processes and formulation development.

Storage, Handling, and Safety

Storage: Store zinc acetate dihydrate in a tightly sealed container in a cool, dry, well-ventilated area away from incompatible materials such as strong acids, strong bases, and oxidizing agents. Recommended storage temperature is ambient (15–25 °C). Protect from moisture to prevent caking and maintain accurate weighing.

Handling: Use standard laboratory personal protective equipment (PPE) including nitrile gloves, safety glasses, and a lab coat. Work in a well-ventilated area or fume hood when handling large quantities or fine powders to avoid inhalation of dust.

Safety: Zinc acetate dihydrate is classified as harmful if swallowed and is irritating to eyes and skin. It is harmful to aquatic organisms with long-lasting effects. Dispose of waste in accordance with local environmental regulations. Consult the Safety Data Sheet (SDS) for full hazard information before use.
