Description

Iodide-Starch Solution is a well-defined chemical reagent primarily used as a sensitive indicator for the detection of oxidizing agents. Its core value lies in the formation of a deep blue iodine-starch complex, providing a clear visual endpoint in analytical procedures. This solution is essential for laboratories and quality control departments in the pharmaceutical, chemical, and water treatment industries, where precise oxidant detection is critical for process validation and safety.

Application

• Analytical Chemistry: As a standard indicator for iodometric titrations to determine the concentration of oxidizing agents like chlorine, peroxides, and ozone.
• Water Quality Testing: For the detection and semi-quantitative analysis of residual chlorine, bromine, and other disinfectants in potable and wastewater.
• Pharmaceutical Quality Control: Used in compendial testing methods (e.g., USP, EP) for the assay of substances that can be determined by redox titration.
• Food & Beverage Industry: Testing for peroxides in oils and fats, and for residual sterilants on processing equipment.
• Educational & Research Laboratories: A fundamental reagent for teaching redox chemistry and for research involving oxidation-reduction reactions.
• Industrial Process Monitoring: On-site testing for oxidizers in chemical manufacturing, pulp & paper bleaching, and swimming pool sanitation.

Quality Control

Our Iodide-Starch Solution is manufactured under strict quality management protocols. Each batch is tested to ensure consistent sensitivity, clarity, and performance as a redox indicator. We provide comprehensive Certificates of Analysis (COA) with key parameters such as reactivity, color transition point, and stability. The solution is prepared following standard analytical reagent practices suitable for general laboratory and industrial use.

Storage

Preserve in a tightly closed amber container, protected from light. Store at a controlled room temperature (15-25°C). This solution is light-sensitive and easily oxidized; prolonged exposure to air or light will degrade its sensitivity. For optimal shelf life, store under recommended conditions and avoid contamination.
