A reagent used for the determination of iron.
Organic chemicals that form two or more coordination links with an iron ion. Once coordination has occurred, the complex formed is called a chelate. The iron-binding porphyrin group of hemoglobin is an example of a metal chelate found in biological systems.
Chemicals that bind to and remove ions from solutions. Many chelating agents function through the formation of COORDINATION COMPLEXES with METALS.
A metallic element with atomic symbol Fe, atomic number 26, and atomic weight 55.85. It is an essential constituent of HEMOGLOBINS; CYTOCHROMES; and IRON-BINDING PROTEINS. It plays a role in cellular redox reactions and in the transport of OXYGEN.

'2,2'-Dipyridyl is an organic compound with the formula (C5H4N)2. It is a bidentate chelating ligand, which means that it can form stable coordination complexes with many metal ions by donating both of its nitrogen atoms to the metal. This ability to form complexes makes '2,2'-Dipyridyl useful in various applications, including as a catalyst in chemical reactions and as a reagent in the analysis of metal ions.

The compound is a solid at room temperature and has a molecular weight of 108.13 g/mol. It is soluble in organic solvents such as ethanol, acetone, and dichloromethane, but is insoluble in water. '2,2'-Dipyridyl is synthesized by the reaction of pyridine with formaldehyde and hydrochloric acid.

In medical contexts, '2,2'-Dipyridyl may be used as a reagent in diagnostic tests to detect the presence of certain metal ions in biological samples. However, it is not itself a drug or therapeutic agent.

Iron chelating agents are medications that bind to iron in the body, forming a stable complex that can then be excreted from the body. These agents are primarily used to treat iron overload, a condition that can occur due to frequent blood transfusions or certain genetic disorders such as hemochromatosis. By reducing the amount of iron in the body, these medications can help prevent or reduce damage to organs such as the heart and liver. Examples of iron chelating agents include deferoxamine, deferasirox, and deferiprone.

Chelating agents are substances that can bind and form stable complexes with certain metal ions, preventing them from participating in chemical reactions. In medicine, chelating agents are used to remove toxic or excessive amounts of metal ions from the body. For example, ethylenediaminetetraacetic acid (EDTA) is a commonly used chelating agent that can bind with heavy metals such as lead and mercury, helping to eliminate them from the body and reduce their toxic effects. Other chelating agents include dimercaprol (BAL), penicillamine, and deferoxamine. These agents are used to treat metal poisoning, including lead poisoning, iron overload, and copper toxicity.

In the context of medicine, iron is an essential micromineral and key component of various proteins and enzymes. It plays a crucial role in oxygen transport, DNA synthesis, and energy production within the body. Iron exists in two main forms: heme and non-heme. Heme iron is derived from hemoglobin and myoglobin in animal products, while non-heme iron comes from plant sources and supplements.

The recommended daily allowance (RDA) for iron varies depending on age, sex, and life stage:

* For men aged 19-50 years, the RDA is 8 mg/day
* For women aged 19-50 years, the RDA is 18 mg/day
* During pregnancy, the RDA increases to 27 mg/day
* During lactation, the RDA for breastfeeding mothers is 9 mg/day

Iron deficiency can lead to anemia, characterized by fatigue, weakness, and shortness of breath. Excessive iron intake may result in iron overload, causing damage to organs such as the liver and heart. Balanced iron levels are essential for maintaining optimal health.
