Chemical Structure
Description
(S)-2-amino-1-(3,4-dihydroisoquinolin-2(1H)-yl)-3-(1H-indol-3-yl)propan-1-one hydrochloride (CAS 1217444-72-8), molecular formula C20H21N3OHCl and molecular weight 355.87 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, (S)-2-amino-1-(3,4-dihydroisoquinolin-2(1H)-yl)-3-(1H-indol-3-yl)propan-1-one hydrochloride (C20H21N3OHCl) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 355.87 g/mol, it falls into the moderately-high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
