Used as a reference standard in analytical laboratories to quantify sucralose in food, beverages, and pharmaceutical products. Commonly employed in high-performance liquid chromatography (HPLC) and liquid chromatography-mass spectrometry (LC-MS) methods to ensure accurate detection and measurement. Helps maintain quality control in manufacturing processes and supports compliance with food safety regulations. Also used in research settings to study stability, degradation, and metabolism of sucralose.
