Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including N-Ethyl-N-((3-hydroxy-9-oxo-9H-fluoren-2-yl)methyl)ethanaminium chloride.
N-Ethyl-N-((3-hydroxy-9-oxo-9H-fluoren-2-yl)methyl)ethanaminium chloride (CAS 42839-81-6) is a high-purity analytical reference standard with the molecular formula C18H20NO2Cl and a molecular weight of 317.81 g/mol.
N-Ethyl-N-((3-hydroxy-9-oxo-9H-fluoren-2-yl)methyl)ethanaminium chloride (C18H20NO2Cl) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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), N-Ethyl-N-((3-hydroxy-9-oxo-9H-fluoren-2-yl)methyl)ethanaminium chloride 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.
