Chemical Structure
Description
(4-Hydroxy-1-naphthalenyl)(1-pentyl-1H-indol-3-yl)methanone (CAS 1393345-76-0) is a high-purity analytical reference standard with the molecular formula C24H23NO2 and a molecular weight of 357.44 g/mol.
(4-Hydroxy-1-naphthalenyl)(1-pentyl-1H-indol-3-yl)methanone (C24H23NO2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
