Chemical Structure
Description
4-methyl-2-(pyrrolidin-3-yl)pyridine dihydrochloride (CAS 1909347-64-3) is a high-purity analytical reference standard with the molecular formula C10H14N2HCl and a molecular weight of 198.69 g/mol.
The molecular framework of 4-methyl-2-(pyrrolidin-3-yl)pyridine dihydrochloride (C10H14N2HCl) 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. 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).
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), 4-methyl-2-(pyrrolidin-3-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.
