A-2089 Starch Soluble

Starch Soluble A-2089 is supplied as a fine, white crystalline powder specially processed for excellent solubility in hot water. As an AR Grade reagent, it is manufactured under strict quality control to ensure minimal impurities that could interfere with precise chemical and biochemical analyses. In redox titrations, soluble starch forms a characteristic deep-blue complex with triiodide ions, making it an essential reagent for accurate endpoint detection in iodometric methods. Main Features Analytical Reagent (AR) Grade Quality Meets stringent purity standards, ensuring suitability for quantitative analysis and research-level laboratory applications. High Sensitivity Iodine Indicator Provides a sharp and distinct color change from colorless to deep blue at the titration endpoint, enabling precise determination of iodine concentration. Excellent Solubility Specially processed to dissolve clearly in boiling water, forming a transparent solution that does not obscure visual titration results. Biological and Enzymatic Applications Commonly used as a nutrient component in microbiological culture media and as a substrate for enzymatic activity assays involving amylase. Stabilized Formulation Manufactured to ensure long shelf life—up to 60 months when stored in a cool, dry environment—supporting consistent performance over time.
