Description

Application

• Rapid and Comprehensive Analysis of 41 Harmful Substances in Multi-Matrix Products by Gas Chromatography-Mass Spectrometry Using Matrix-Matching Calibration Strategy.: This research uses gas chromatography-mass spectrometry (GC-MS) to analyze harmful substances across various matrices. Dichloromethane is employed as a solvent in the preparation phase, highlighting its application in ensuring accurate and efficient analytical results (Wang Y et al., 2024).


• Brunonianines D-F, three new C19-diterpenoid alkaloids from the Delphinium brunonianum, with therapeutic effect on ovarian cancer in vitro and in vivo.: This study identifies new alkaloids with potential anti-cancer properties, where dichloromethane is utilized in the extraction and isolation processes. Its effectiveness in separating and preserving delicate compounds is critical for their pharmacological evaluation (Li Q et al., 2024).


• LC-HRMS and GC-MS Profiling of Urine Free Cortisol, Cortisone, 6Β-, and 18-Hydroxycortisol for the Evaluation of Glucocorticoid and Mineralocorticoid Disorders.: Utilizes LC-HRMS and GC-MS to profile hormones in urine, with dichloromethane being crucial in the extraction process. This method ensures precision and sensitivity in hormone measurement, essential for diagnosing endocrine disorders (Casals G et al., 2024).


• Determination of vancomycin and meropenem in serum and synovial fluid of patients with prosthetic joint infections using UPLC-MS/MS.: Features a method to measure antibiotics in biological fluids, where dichloromethane is used to prepare samples. This study underscores the solvent′s role in achieving high resolution and detection limits in clinical diagnostics (He J et al., 2024).

Features and Benefits
