Chemical Structure
Description
CATO supplies 3-(2-Chloroethyl)pyridine hydrochloride (CAS 4226-36-2), a certified reference material (molecular formula C7H8ClNHCl, MW 178.06 g/mol) for analytical method development and quality control.
Structurally, 3-(2-Chloroethyl)pyridine hydrochloride (C7H8ClNHCl) contains a nitrile group, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 178.06 g/mol, it falls into the medium-molecular-weight range. 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-(2-Chloroethyl)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.
