(R)-5-(2-((5-cyano-2-(2-methoxyethoxy)phenyl)amino)pyrimidin-4-yl)-3-(hydroxymethyl)-3-methylindoline-7-carbonitrile (CAS 2113617-57-3), molecular formula C25H24N6O3 and molecular weight 456.50 g/mol, is a CATO reference standard with documented purity and traceability.

(R)-5-(2-((5-cyano-2-(2-methoxyethoxy)phenyl)amino)pyrimidin-4-yl)-3-(hydroxymethyl)-3-methylindoline-7-carbonitrile (C25H24N6O3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
