Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
5-fluorospiro[2,3-dihydro-1H-isoquinoline-4,1'-cyclopropane];hydrochloride (CAS 1203684-97-2) is a high-purity analytical reference standard with the molecular formula C11H18FNHCl and a molecular weight of 219.73 g/mol.
Structurally, 5-fluorospiro[2,3-dihydro-1H-isoquinoline-4,1'-cyclopropane];hydrochloride (C11H18FNHCl) contains a nitrile group, fluorine/chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 219.73 g/mol, it falls into the medium-molecular-weight range. 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.
