Description
As a certified reference material (CRM), (9H-Fluoren-9-yl)methyl pyrrolidin-3-ylcarbamate hydrochloride 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.
(9H-Fluoren-9-yl)methyl pyrrolidin-3-ylcarbamate hydrochloride (CAS 1220040-24-3) is a high-purity analytical reference standard with the molecular formula C19H20N2O2HCl and a molecular weight of 344.84 g/mol.
(9H-Fluoren-9-yl)methyl pyrrolidin-3-ylcarbamate hydrochloride (C19H20N2O2HCl) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
