Chemical Structure
Description
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
3-Chloro-6-hydrazono-1,6-dihydropyridazine hydrate (CAS 1588441-01-3) is a high-purity analytical reference standard with the molecular formula C4H5ClN4H2O and a molecular weight of 162.58 g/mol.
3-Chloro-6-hydrazono-1,6-dihydropyridazine hydrate (C4H5ClN4H2O) contains 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.
