Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 360.46 g/mol gives Desoximetasone EP Impurity F distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Desoximetasone EP Impurity F (CAS 184899-80-7) is a high-purity analytical reference standard with the molecular formula C22H29FO3 and a molecular weight of 360.46 g/mol.
Based on its molecular formula C22H29FO3, Desoximetasone EP Impurity F contains a steroid core, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 360.46 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), Desoximetasone EP Impurity F meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
