Methyl ((S)-3-methyl-1-oxo-1-((S)-2-(5-(6-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)naphthalen-2-yl)-1H-imidazol-2-yl)pyrrolidin-1-yl)butan-2-yl)carbamate (CAS 1228553-66-9), molecular formula C30H39BN4O5 and molecular weight 546.47 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Methyl ((S)-3-methyl-1-oxo-1-((S)-2-(5-(6-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)naphthalen-2-yl)-1H-imidazol-2-yl)pyrrolidin-1-yl)butan-2-yl)carbamate (C30H39BN4O5) is characterized by a steroid 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
