Chemical Structure
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.
1-(2,3-Dimethyl-1H-indol-1-yl)-3-((2-hydroxyethyl)amino)propan-2-ol oxalate (CAS 436099-60-4), molecular formula C15H22N2O2C2H2O4 and molecular weight 352.39 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1-(2,3-Dimethyl-1H-indol-1-yl)-3-((2-hydroxyethyl)amino)propan-2-ol oxalate (C15H22N2O2C2H2O4) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
