Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 2-hydrazinyl-4,5-dihydro-1H-imidazole hydroiodide (CAS 39889-17-3), a certified reference material (molecular formula HIC3H8N4, MW 228.03 g/mol) for analytical method development and quality control.
The molecular framework of 2-hydrazinyl-4,5-dihydro-1H-imidazole hydroiodide (HIC3H8N4) is characterized by iodine 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
As a certified reference material (CRM), 2-hydrazinyl-4,5-dihydro-1H-imidazole hydroiodide 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.
