Chemical Structure
Description
Methyl 2-{1-[4-(1H-imidazol-1-yl)phenyl]ethylidene}-1-hydrazinecarboxylate (CAS 303148-80-3) is a high-purity analytical reference standard with the molecular formula C13H14N4O2 and a molecular weight of 258.28 g/mol.
The molecular framework of Methyl 2-{1-[4-(1H-imidazol-1-yl)phenyl]ethylidene}-1-hydrazinecarboxylate (C13H14N4O2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. 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.
