Triclosan standard solution is primarily used as a reference material in analytical laboratories for the accurate quantification and detection of triclosan in various samples. It is essential in environmental monitoring to measure triclosan levels in water, soil, and wastewater, helping assess contamination and ecological impact. The standard solution is also used in quality control for consumer products such as antimicrobial soaps, toothpastes, cosmetics, and textiles to ensure compliance with regulatory limits. In research settings, it supports studies on triclosan’s stability, degradation, and potential health effects. Its precise concentration allows for calibration of instruments like HPLC and GC-MS, ensuring reliable and reproducible results.
