Chemical Structure
Description
[(5s)-spiro[5,7-dihydrocyclopenta[b]pyridine-6,4-piperidin-1-ium]-5-yl]ammonium;dichloride (C12H19N3Cl) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
[(5s)-spiro[5,7-dihydrocyclopenta[b]pyridine-6,4-piperidin-1-ium]-5-yl]ammonium;dichloride (CAS 2377355-48-9), molecular formula C12H19N3Cl and molecular weight 240.75 g/mol, is a CATO reference standard with documented purity and traceability.
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.
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.
