Zinc selenite, with the CAS number 13597 - 46 - 1, is a chemical compound that combines zinc and selenium in an oxidation state. Our high - quality zinc selenite product offers the best price in the market. The chemical formula of zinc selenite is ZnSeO₃. It exists as a white to off - white crystalline powder. The molecular weight of zinc selenite is approximately [calculate the exact molecular weight]. It has good chemical stability under normal conditions but may react with strong acids or reducing agents. This product is carefully manufactured to meet strict quality standards, ensuring high purity and consistent quality.
1. **Nutritional Supplements**: Zinc and selenium are essential trace elements for the human body. Zinc is involved in many enzymatic reactions, immune function, and growth and development. Selenium is an important antioxidant, which can protect cells from oxidative damage. Our zinc selenite can be used as a raw material for nutritional supplements, helping to maintain the normal physiological functions of the human body.
2. **Agricultural Applications**: In agriculture, zinc selenite can be used as a trace element fertilizer. Zinc is necessary for plant enzyme activation and growth regulation, while selenium can enhance the stress resistance of plants, such as resistance to drought, disease, and heavy metal stress. By adding zinc selenite to the soil, it can improve the nutritional status of plants and increase crop yields.
3. **Industrial Catalysts**: Due to its unique chemical properties, zinc selenite can be used as a catalyst in some chemical reactions. It can promote the reaction rate and improve the selectivity of the reaction, which is important in the chemical industry for the synthesis of various organic and inorganic compounds.
1. **For Nutritional Supplements**: If used in the production of nutritional supplements, it is recommended to follow the relevant regulations and standards. Usually, it needs to be accurately weighed and mixed with other raw materials according to the formula. The dosage should be determined based on the target population and the specific product requirements. For example, for adult nutritional supplements, the recommended daily intake of zinc and selenium should be within the safe range.
2. **In Agriculture**: When used as a fertilizer, it can be applied to the soil before sowing or during the growth period of crops. The application rate should be adjusted according to the soil conditions and crop types. It can be evenly spread on the soil surface and then plowed into the soil, or dissolved in water and sprayed on the leaves of plants.
3. **As Industrial Catalysts**: In industrial applications, the appropriate amount of zinc selenite should be added to the reaction system according to the reaction conditions and requirements. It is necessary to pay attention to the reaction temperature, pressure, and reaction time to ensure the effectiveness of the catalyst.
1. **Nutritional Supplement Case**: A health product company used our zinc selenite to produce a multi - vitamin and mineral supplement. After a six - month market trial, they found that consumers who took the supplement regularly showed improved immune function. Blood tests of the consumers indicated that the levels of zinc and selenium in their bodies were within the normal range, and the incidence of colds and other minor diseases decreased significantly compared to the control group. This shows that our zinc selenite can effectively supplement the trace elements needed by the human body and improve health.
2. **Agricultural Case**: A farm in a certain region applied our zinc selenite as a fertilizer to the wheat fields. The wheat grew more vigorously, with stronger stalks and larger ears. The yield per mu increased by about 15% compared to the previous year. At the same time, the wheat showed better resistance to rust and other diseases, reducing the use of pesticides. This demonstrates the positive impact of zinc selenite on crop growth and yield improvement in agriculture.
3. **Industrial Catalyst Case**: A chemical factory used our zinc selenite as a catalyst in the synthesis of a certain organic compound. The reaction time was significantly reduced, and the yield of the product increased by 20%. The selectivity of the reaction also improved, reducing the generation of by - products. This shows that our zinc selenite can play an important role in industrial chemical reactions.
