Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
6,7-Dihydro-5H-cyclopenta[b]pyridin-3-ylmethanamine dihydrochloride (CAS 115019-53-9) is a high-purity analytical reference standard with the molecular formula C9H12N2HCl and a molecular weight of 184.67 g/mol.
The molecular framework of 6,7-Dihydro-5H-cyclopenta[b]pyridin-3-ylmethanamine dihydrochloride (C9H12N2HCl) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
