Description

[R-(R*,R*)]-Tartaric Acid, Iron Potassium Salt is a coordination complex of iron and potassium with tartaric acid, a compound recognized for its role as a chiral auxiliary and metal chelator. This specific stereoisomer is valued for its defined molecular geometry, which is critical in applications requiring precise stereochemical control. It serves as a key intermediate and reagent for pharmaceutical synthesis, asymmetric catalysis, and advanced material science, where its ability to form stable complexes with transition metals is leveraged.

Application

• Pharmaceutical Intermediate: Used in the synthesis of chiral active pharmaceutical ingredients (APIs) and as a resolving agent.
• Asymmetric Catalyst Precursor: Serves as a ligand or precursor in the preparation of catalysts for enantioselective chemical reactions.
• Analytical Chemistry: Employed as a standard or reagent in complexometric titrations and metal ion analysis.
• Nutritional & Food Grade Additives: Potential use as a source of bioavailable iron in fortified food products or dietary supplements (subject to appropriate grade and regulatory approval).
• Material Science: Acts as a chelating agent in the preparation of functional materials, such as metal-organic frameworks (MOFs) or surface coatings.
• Laboratory Research: Utilized in academic and industrial R&D for studying chiral induction and metal-ligand interactions.
