1,2-dihydrospiro[indole-3,3’-pyrrolidine] dihydrochloride CAS 1909316-65-9

Description

The occurrence of 1,2-dihydrospiro[indole-3,3’-pyrrolidine] dihydrochloride is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1,2-dihydrospiro[indole-3,3’-pyrrolidine] dihydrochloride (CAS 1909316-65-9), molecular formula C11H14N2HCl and molecular weight 210.70 g/mol, is a CATO reference standard with documented purity and traceability.

1,2-dihydrospiro[indole-3,3’-pyrrolidine] dihydrochloride (C11H14N2HCl) 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
