Used as a reference standard in analytical laboratories for the quantification and detection of sulfameter residues in environmental samples, animal tissues, and food products such as milk and honey. Commonly employed in high-performance liquid chromatography (HPLC) and liquid chromatography-mass spectrometry (LC-MS) methods to ensure accuracy and reliability in residue analysis. Helps monitor compliance with regulatory limits for sulfonamide antibiotics in agricultural and veterinary practices.
