oksinaatin

Oksinaatin is a term that can refer to several different chemical compounds, primarily in the context of analytical chemistry and organic synthesis. One common usage refers to the organic compound derived from oxine, also known as 8-hydroxyquinoline. This compound, often called "oxinate" in a general sense, is a chelating agent. It is particularly known for its ability to form stable complexes with a wide range of metal ions. These metal oxinate complexes can have distinct colors and solubilities, which makes them useful for gravimetric analysis, spectrophotometric determination, and the separation of metals. For example, aluminum oxinate is a fluorescent compound used in analytical chemistry.

Another context for "oksinaatin" might arise in discussions of specific metal complexes formed with oxine. For instance, magnesium oxinate is a well-known compound used in gravimetric analysis for the quantitative determination of magnesium. The formation of these metal oxinate complexes is often a pH-dependent process, allowing for selective precipitation and analysis. The general structure of an oxinate ligand involves the deprotonated form of 8-hydroxyquinoline, which can then coordinate to a metal ion through both the nitrogen atom of the quinoline ring and the oxygen atom of the hydroxyl group. The specific properties and applications of an "oksinaatin" will therefore depend on the particular metal ion involved.
