Description
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.
[(3Z)-1-[(2,6-Dichlorophenyl)methyl]-2-oxo-2,3-dihydro-1H-indol-3-ylidene]amino 4-chlorobenzoate (CAS 252579-08-1) is a high-purity analytical reference standard with the molecular formula C22H13Cl3N2O3 and a molecular weight of 459.71 g/mol.
Based on its molecular formula C22H13Cl3N2O3, [(3Z)-1-[(2,6-Dichlorophenyl)methyl]-2-oxo-2,3-dihydro-1H-indol-3-ylidene]amino 4-chlorobenzoate contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 459.71 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
