Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
(S)-1-(1-(3-fluorobenzyl)-1H-benzo[d]imidazol-2-yl)pyrrolidin-3-ol (CAS 1353998-32-9) is a high-purity analytical reference standard with the molecular formula C18H18FN3O and a molecular weight of 311.35 g/mol.
(S)-1-(1-(3-fluorobenzyl)-1H-benzo[d]imidazol-2-yl)pyrrolidin-3-ol (C18H18FN3O) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
