Chemical Structure
Description
The occurrence of 5-Hydrazino-2(1H)-quinolinone HCl is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
5-Hydrazino-2(1H)-quinolinone HCl (CAS 372078-45-0) is a high-purity analytical reference standard with the molecular formula C9H9N3OHCl and a molecular weight of 211.65 g/mol.
5-Hydrazino-2(1H)-quinolinone HCl (C9H9N3OHCl) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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), 5-Hydrazino-2(1H)-quinolinone HCl 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.
