898763-23-0 {2-[(2,5-Dihydro-1H-pyrrol-1-yl)methyl]phenyl}(2,4-dimethylphenyl)methanone DTXSID20643933 CAS 898763-23-0

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.

898763-23-0 {2-[(2,5-Dihydro-1H-pyrrol-1-yl)methyl]phenyl}(2,4-dimethylphenyl)methanone DTXSID20643933 (CAS 898763-23-0), molecular formula C20H21NO and molecular weight 291.39 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C20H21NO, 898763-23-0 {2-[(2,5-Dihydro-1H-pyrrol-1-yl)methyl]phenyl}(2,4-dimethylphenyl)methanone DTXSID20643933 contains a steroid core, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 291.39 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.
