Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-(Pyrrolidin-2-yl)pyridine dihydrochloride.
3-(Pyrrolidin-2-yl)pyridine dihydrochloride (CAS 67209-89-6) is a high-purity analytical reference standard with the molecular formula C9H12N2HCl and a molecular weight of 184.67 g/mol.
Based on its molecular formula C9H12N2HCl, 3-(Pyrrolidin-2-yl)pyridine dihydrochloride contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 184.67 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
As a certified reference material (CRM), 3-(Pyrrolidin-2-yl)pyridine dihydrochloride 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.
