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.
2-(2-(4,5-Dihydro-1H-imidazol-2-yl)hydrazinyl)pyridine (CAS 803617-97-2), molecular formula C8H11N5 and molecular weight 177.21 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-(2-(4,5-Dihydro-1H-imidazol-2-yl)hydrazinyl)pyridine (C8H11N5) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group. 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).
CATO manufactures 2-(2-(4,5-Dihydro-1H-imidazol-2-yl)hydrazinyl)pyridine under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
