Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-Hydrazinyl-4,5-dihydro-1h-imidazole.
2-Hydrazinyl-4,5-dihydro-1h-imidazole (CAS 51420-32-7), molecular formula C3H8N4 and molecular weight 100.12 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-Hydrazinyl-4,5-dihydro-1h-imidazole (C3H8N4) is characterized by 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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), 2-Hydrazinyl-4,5-dihydro-1h-imidazole 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.
