Chemical Structure
Description
4-(3-Chloropropyl)pyridine hydrochloride (CAS 17944-59-1) is a high-purity analytical reference standard with the molecular formula C8H10ClNHCl and a molecular weight of 192.08 g/mol.
The molecular framework of 4-(3-Chloropropyl)pyridine hydrochloride (C8H10ClNHCl) is characterized by a nitrile group, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, 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-(3-Chloropropyl)pyridine 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.
