5-Chloro-2-((diphenylmethylenE)hydrazono)-1,2-dihydropyridine CAS 1135229-67-2

Description

The occurrence of 5-Chloro-2-((diphenylmethylenE)hydrazono)-1,2-dihydropyridine is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

5-Chloro-2-((diphenylmethylenE)hydrazono)-1,2-dihydropyridine (CAS 1135229-67-2) is a high-purity analytical reference standard with the molecular formula C18H14ClN3 and a molecular weight of 307.78 g/mol.

5-Chloro-2-((diphenylmethylenE)hydrazono)-1,2-dihydropyridine (C18H14ClN3) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; 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.

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.
