Synonyms: ----
CAS Number: Dihydrate 5970-45-6 (Anhydrous 557-34-6), Molecular Weight: 219.51, Chemical Formula: (CH3COO)2Zn-2H2O, EINECS EC Number: 209-170-2, FEMA: ----,

Zinc acetate is a salt with the formula Zn(O2CCH3)2, which commonly occurs as the dihydrate Zn(O2CCH3)2(H2O)2. Both the hydrate and the anhydrous forms are colorless solids that are commonly used in chemical synthesis and as dietary supplements. Zinc acetates are prepared by the action of acetic acid on zinc carbonate or zinc metal. When used as a food additive, it has the E number E650.

We offer BP USP IP Analytical Reagent Grade of Zinc Acetate.

Specifications of Zinc Acetate USP Grade:
C4H6O4Zn-2H2O --- 219.50
C4H6O4Zn --- 183.48
Acetic acid, zinc salt, dihydrate;    
Zinc acetate dihydrate CAS 5970-45-6.
Zinc acetate anhydrous CAS 557-34-6.

DEFINITION
Zinc Acetate contains NLT 98.0% and NMT 102.0% of C4H6O4Zn-2H2O.

IDENTIFICATION
A. Identification Tests General, Zinc: A 50 mg/mL solution meets the requirements.
B. Identification Tests General, Acetate: A 50 mg/mL solution meets the requirements.

ASSAY
Procedure:
Sample solution: To 400 mg of Zinc Acetate in 100 mL of water add 5 mL of ammonia–ammonium chloride buffer TS and 0.1 mL of eriochrome black.
Analysis: Titrate the Sample solution with 0.05 M EDTA disodium VS until the solution is deep blue in color. Each mL of 0.05 M EDTA disodium is equivalent to 10.98 mg of zinc acetate dihydrate (C4H6O4Zn-2H2O).
Acceptance criteria: 98.0%–102.0%

Chloride and Sulfate, Chloride: A 1.5-g portion shows no more chloride than corresponds to 0.10 mL of 0.020 N hydrochloric acid (0.005%).
Chloride and Sulfate, Sulfate: A 1.0-g portion shows no more sulfate than corresponds to 0.10 mL of 0.020 N sulfuric acid (0.010%).
Arsenic: NMT 3 ppm
Lead: To pass the test.
Acceptance criteria: --- 0.002%.
Alkalies and Alkaline Earths:
Sample solution: Dissolve 2.0 g in 150 mL of water in a 200-mL volumetric flask. Add sufficient ammonium sulfide to precipitate the zinc completely and dilute with water to volume. Pass through a dry filter, rejecting the first portion of the filtrate.
Analysis: To 100 mL of the filtrate add 5 drops of sulfuric acid. Evaporate to dryness and ignite.
Acceptance criteria: The weight of the residue does not exceed 2 mg (0.2%).
Insoluble Matter: A 20-g portion, dissolved in 150 mL of water containing 1 mL of glacial acetic acid, shows NMT 1.0 mg of insoluble matter (0.005%).
pH: 6.0–8.0, in a solution (1 in 20)
Packaging and Storage: Preserve in tight containers.


Specifications of Zinc Acetate BP Ph Eur Grade:
C4H6O4Zn-2H2O --- 219.5 --- CAS 5970-45-6
Action and use: Astringent.

DEFINITION
Content: 99.0 per cent to 101.0 per cent of C4H6O4Zn,2H2O.

CHARACTERS
Appearance: White or almost white crystalline powder or flakes.
Solubility: Freely soluble in water, soluble in ethanol (96 per cent).

IDENTIFICATION
A. It gives reaction of acetates.
B. It gives the reaction of zinc.

TESTS
Solution S: Dissolve 10.0 g in carbon dioxide-free water prepared from distilled water and dilute to 100 mL with the same solvent.
Appearance of solution: Solution S is clear and colourless.
pH: 5.8 to 7.0.
Dilute 10 mL of solution S to 20 mL with carbon dioxide-free water.
Reducing substances: Boil for 5 min a mixture of 10 mL of solution S, 90 mL of water, 5 mL of dilute sulfuric acid and 1.5 mL of a 0.3 g/L solution of potassium permanganate. The pink colour of the solution remains.
Chlorides: Maximum 50 ppm.
Sulfates: Maximum 100 ppm, determined on solution S.

Arsenic: Maximum 2 ppm, determined on 0.5 g.
Cadmium: Maximum 2 ppm.
Copper: Maximum 50 ppm.
Iron: Maximum 50 ppm.
Lead: Maximum 10 ppm.

ASSAY
Dissolve 0.200 g in 5 mL of dilute acetic acid R. Carry out the complexometric titration of zinc.
1 mL of 0.1 M sodium EDTA is equivalent to 21.95 mg of C4H6O4Zn,2H2O.
