Ammonium Ferric Citrate (CAS No. 1185 - 57 - 5) is a high - quality chemical compound. It is a brown or greenish - brown powder. The brown form is usually more soluble in water compared to the green form. Chemically, it is a complex salt composed of ammonium, iron, and citrate ions. The molecular formula can vary, but it generally represents a combination of these three components.
The product is known for its high purity, which makes it suitable for a wide range of applications. It has a good stability under normal storage conditions, but it should be kept away from strong oxidizing agents and acids. The pH value of its aqueous solution is in the slightly acidic to neutral range, which is an important parameter for many applications.
1. **Pharmaceutical Industry**: Ammonium Ferric Citrate is used as an iron supplement in pharmaceuticals. Iron is an essential element for the human body, and this compound can be easily absorbed, helping to treat or prevent iron - deficiency anemia. It is also used in some liquid medications due to its solubility properties.
2. **Photography**: In the field of photography, it is used in the making of blueprints. The compound reacts with light in a specific way, allowing for the creation of detailed images on paper. It is a key component in the traditional cyanotype process.
3. **Food Industry**: In some cases, it can be used as a food additive. It can be used to add iron to food products, especially in fortified cereals and other nutritional products, to enhance their iron content.
4. **Laboratory Research**: It is widely used in laboratories for various chemical reactions and analytical purposes. For example, it can be used as a source of iron ions in chemical synthesis and in the study of iron - related biological processes.
1. **In Pharmaceuticals**: When used as an iron supplement, the dosage should be determined by a doctor based on the patient's age, gender, and the severity of iron deficiency. It is usually taken orally with water, preferably after meals to reduce potential gastrointestinal discomfort.
2. **In Photography**: For the cyanotype process, a solution of Ammonium Ferric Citrate is prepared. The solution is then evenly coated on a suitable paper surface using a brush or a roller. After drying in a dark environment, the paper is exposed to light under a negative image. After exposure, the paper is developed in water to reveal the image.
3. **In Food Industry**: When used as a food additive, it should be added in accordance with the relevant food safety regulations. It is usually dissolved in a small amount of water first and then mixed thoroughly with the food product during the manufacturing process.
4. **In Laboratory Research**: The usage in laboratories depends on the specific experiment. It can be dissolved in an appropriate solvent, and the concentration of the solution should be adjusted according to the requirements of the reaction. Safety precautions such as wearing gloves and goggles should be taken during handling.
1. **Pharmaceutical Case**: A medical research institution conducted a study on patients with mild iron - deficiency anemia. They administered Ammonium Ferric Citrate supplements to a group of patients over a period of three months. After the treatment, blood tests showed a significant increase in the patients' hemoglobin levels, indicating the effectiveness of the compound in treating iron deficiency.
2. **Photography Case**: A photography enthusiast used Ammonium Ferric Citrate to create blueprints of botanical specimens. By carefully controlling the coating thickness and exposure time, the resulting blueprints had high - resolution details of the plant structures, which were highly appreciated in a local art exhibition.
3. **Food Industry Case**: A food company added Ammonium Ferric Citrate to its cereal products. After market research, they found that customers were more likely to choose their fortified cereals due to the added iron content, which led to an increase in sales.
