Definition
Lithium succinate refers to a chemical compound consisting of lithium ions combined with the succinate anion, which is the doubly deprotonated form of succinic acid (C₄H₆O₄). The most common stoichiometry is the di‑lithium salt, with the formula Li₂C₄H₄O₄.
Overview
Lithium succinate is a relatively obscure lithium salt compared with more widely studied lithium compounds such as lithium carbonate or lithium chloride. It is not prominently featured in major chemical or pharmaceutical reference works, and detailed information regarding its synthesis, physical properties, or practical applications is scarce in the publicly accessible literature.
Etymology / Origin
The name derives from two components:
- Lithium – a lightweight alkali metal (atomic number 3) commonly used in various inorganic salts.
- Succinate – the anionic form of succinic acid, a dicarboxylic acid historically obtained from the oxidation of succinate (a term originating from “succus,” Latin for “juice” or “sap”).
Characteristics
- Chemical formula: Li₂C₄H₄O₄ (for the fully neutralized di‑lithium salt).
- Molecular weight: Approximately 151.95 g·mol⁻¹.
- Physical state: Expected to be a solid at room temperature, likely crystalline, similar to other inorganic lithium carboxylates.
- Solubility: Carboxylate salts of lithium are generally soluble in water; however, specific solubility data for lithium succinate are not widely documented.
- Stability: As an inorganic salt, it is presumed stable under standard conditions, but detailed thermal or chemical stability data are not available in mainstream sources.
Related Topics
- Succinic acid: A biodegradable dicarboxylic acid used in the production of polymers, food additives, and pharmaceuticals.
- Lithium salts: Compounds such as lithium carbonate, lithium chloride, and lithium hydroxide, which have extensive industrial, medical, and scientific applications.
- Lithium therapy: The medical use of lithium compounds, primarily lithium carbonate, for mood stabilization in bipolar disorder; no confirmed therapeutic role for lithium succinate has been established.
Note on Availability of Information
Accurate and comprehensive information about lithium succinate is not confirmed in standard encyclopedic references, peer‑reviewed journals, or major chemical databases. Consequently, the details provided above are based on general chemical principles and the limited data that can be inferred from the compound’s constituent elements. Further verification from specialized chemical literature would be required to substantiate any specific properties or applications.
