Chemical Structure
Description
CATO supplies N-(2-(Indolin-1-yl)phenyl)-3-phenylpropanamide (CAS 71971-52-3), a certified reference material (molecular formula C23H22N2O, MW 342.43 g/mol) for analytical method development and quality control.
Structurally, N-(2-(Indolin-1-yl)phenyl)-3-phenylpropanamide (C23H22N2O) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 14.0, corresponding to approximately 14 ring(s) or double-bond equivalent(s). With a molecular weight of 342.43 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
