Understanding the fundamental properties and synthesis of key chemical reagents is crucial for effective laboratory practice. NINGBO INNO PHARMCHEM CO.,LTD. offers Alizarin Complexone (CAS 3952-78-1), a compound whose chemical makeup dictates its significant analytical capabilities.

Alizarin Complexone, with the molecular formula C19H15NO8 and a molecular weight of approximately 385.32 g/mol, is characterized by its dihydroxyanthraquinone structure combined with an iminodiacetic acid moiety. This specific arrangement of functional groups is what confers its strong chelating abilities, allowing it to form stable complexes with a variety of metal ions. Typically supplied as a powder ranging in color from white to yellow, orange, or brown, its assay is generally reported at 98% or higher, signifying its purity and suitability for precise analytical work.

While detailed synthesis procedures are proprietary, the preparation of Alizarin Complexone generally involves reactions that link the alizarin core with iminodiacetic acid derivatives. For instance, reactions with formaldehyde and iminodiacetic acid onto an alizarin base are common routes. The careful control of reaction conditions during synthesis is paramount to achieving the desired purity and functionality for its primary applications, such as the Spectrophotometric determination of fluorine and its role as a complexation indicator for metals like calcium and lead.

The stability and solubility characteristics of Alizarin Complexone are also key properties. While slightly soluble in water, it demonstrates better solubility in alkaline solutions or certain organic solvents like DMSO, which is often utilized in its preparation for analytical use. When considering the buy options for Alizarin Complexone, understanding these chemical properties ensures the reagent is used optimally within your specific laboratory protocols. NINGBO INNO PHARMCHEM CO.,LTD. provides this essential reagent to support your analytical needs.
