Used as a reference standard in analytical laboratories for calibration of instruments such as gas chromatographs (GC) and high-performance liquid chromatographs (HPLC). Ensures accurate quantification and identification of methanol in various samples, including environmental, industrial, and biological matrices. Commonly applied in quality control processes for pharmaceuticals, food and beverage testing, and forensic analysis. Also utilized in environmental monitoring to detect methanol contamination in air, water, and soil samples. Provides consistent and reliable results due to its defined concentration and high purity.
