Uses
Different sources of media describe the Uses of 5970-45-6 differently. You can refer to the following data:
1. Zinc acetate is used as a mordant in dyeing textiles; in preserving wood; in manufacturing glazes for painting on ceramics; and as an analytic reagent in measuring albumin, tannin, and phosphate. Other uses are as a crosslinking agent for polymers; and as a supplement in food. The compound is used in medicine as an astringent.
2. Preserving wood; as mordant in dyeing; manufacture of glazes for painting on porcelain. As a reagent in testing for albumin, tannin, urobilin, phosphate, blood.
3. Zinc acetate [Zn(C2H3O2)2] is used as a mordant for dyeing cloth, as a wood preservative,
as a laboratory agent, and as a dietary supplement.
4. Zinc acetate dihydrate is used in the preparation of layered Zn-arylphosphonates with potential application in sorption, ion exchange or catalysis and zinc sulfide nanoparticles coated on silica particles. It is used in dietary and medical applications. It is also used as lozenges for treating the common cold. It is used as a seeding material to grow zinc oxide nanorods on the microfibers of polyethylene terephthalate fabric. In addition, it finds application as wood preservation, production of other zinc salts, ethylene acetate manufacture, and an analytical reagent in various industries. As a plating inhibitor, it is used in nuclear power plant.
General Description
Structure of zinc acetate dehydrate is monoclinic with unit cell dimensions a=14.50, b=5.32 and c=11.02?.
Safety
Zinc acetate is used in topical pharmaceutical formulations and
subcutaneous injections, where it is generally regarded as relatively
nontoxic and nonirritant when used as an excipient. However, zinc
acetate is poisonous by intravenous and intraperitoneal routes; it is
also moderately toxic following oral consumption.
LD50 (mouse, IP): 0.108 g/kg
LD50 (mouse, oral): 0.287 g/kg
LD50 (rat, IP): 0.162 g/kg
LD50 (rat, oral): 0.794 g/kg
storage
Zinc acetate loses water of hydration above 100℃. Zinc acetate
should be stored in an airtight container in a cool, dry, place.
Purification Methods
It crystallises (in poor yield) from hot water or, better, from EtOH. [Beilstein 2 III 193, 2 IV 114.]
Check Digit Verification of cas no
The CAS Registry Mumber 5970-45-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,9,7 and 0 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 5970-45:
(6*5)+(5*9)+(4*7)+(3*0)+(2*4)+(1*5)=116
116 % 10 = 6
So 5970-45-6 is a valid CAS Registry Number.
