Product Description

Copper Gluconate, molecular formula Cu(C6H11O7)2 Molecular weight, 453.84, light blue powder
Copper is a component of many important enzyme systems in the body, which can promote the absorption and utilization of iron and maintain the function of the central nervous system. When copper deficiency occurs, the brittleness of various blood vessels and bones in the human body increases, brain tissue atrophy can also cause melanin loss such as vitiligo and juvenile whitehead.
Copper gluconate (527-09-3) preparation method:
1. It is obtained by the reaction and crystallization of gluconic acid and copper oxide.
2. Obtained by the reaction of gluconate and copper salt.
3. Obtained by the crystallization of sodium gluconate and copper sulfate.
4. After the electrolytic oxidation of glucose into gluconic acid, it is neutralized with copper carbonate and generates sorbitol at the same time.
Content analysis: The sample was accurately weighed with about 1.5g, dissolved in 100ml water in 250ml conical flask, mixed with 2ml acetic acid and 5g potassium iodide, and titrated with 0.1mol/L sodium thiosulfate until light yellow. Add 2g ammonium thiocyanate, mix well, then add 3ml starch test solution (TS-235) and continue titrating until the milky end point. Each mL 0.lmol/L sodium thiosulfate is equivalent to 45.38mg of copper gluconate (C12H22CuO14).
1. Lead: 1g/25ml aqueous solution was prepared as the sample solution, and then determined by GT-18 method.
2. Reducing substance: Accurately weigh the sample of about 1g, transfer it to 250ml conical flask, dissolve in 10ml water, add 25ml basic copper citrate test solution (TS-76), and cover the flask with a small beaker. Bring to a precise boil over low heat for 5 minutes and then cool quickly to room temperature. After adding 25ml 10% acetic acid, 10.0ml 0.0lmol /L iodine solution, 10ml dilute hydrochloric acid solution (TS-117) and 3ml starch solution (TS-235), titrations were made with 0.1mol/L sodium thiosulfate until the blue color disappeared. The mass (mg) of the reducing substance (in D-glucose) is calculated by the formula. The mass of reducing substance (D-glucose) /mg = (v1c1-V2C2)·27 where V1 and c1 are the volume and molar concentration of iodine solution, respectively; V2 and c2 are the volume and molar concentration of sodium thiosulfate solution, respectively. 27 is an empirically measured conversion factor for D-glucose. Identification test: Copper test positive for 1.5% aqueous solution (IT-15). 2. Take 5ml of 10% warm sample solution, add 0.7ml glacial acetic acid and 1ml fresh distilled phenylhydrazine, heat it on steam bath for 30min, and then cool it. The inner surface of the container is rubbed with a glass stirring rod to induce crystallization
