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, forensic analysis, and air or water pollution monitoring where precise measurement of methanol concentration is critical. Also utilized in method validation and verification of analytical procedures to maintain compliance with regulatory standards.
