Chemical Structure
Description
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.
3,4-Dihydro-2H-spiro[naphthalene-1,3'-pyrrolidine] hydrochloride (CAS 73593-94-9), molecular formula C13H17NHCl and molecular weight 223.74 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3,4-Dihydro-2H-spiro[naphthalene-1,3'-pyrrolidine] hydrochloride (C13H17NHCl) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
As a certified reference material (CRM), 3,4-Dihydro-2H-spiro[naphthalene-1,3'-pyrrolidine] hydrochloride meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
