(3S,6S,9S,12R,15S,18S,21S,24S,27R,30S,33S)-27-((2-(Dimethylamino)ethyl)thio)-30-ethyl-33-((1R,2R,E)-1-hydroxy-2-methylhex-4-en-1-yl)-24-(2-hydroxy-2-methylpropyl)-6,9,18-triisobutyl-3,21-diisopropyl-1,4,7,10,12,15,19,25,28-nonamethyl-1,4,7,10,13,16,19,22,25,28,31-undecaazacyclotritriacontan-2,5,8,11,14,17,20,23,26,29,32-undecaone (CAS 210759-10-7) is a high-purity analytical reference standard with the molecular formula C66H120N12O13S and a molecular weight of 1321.80 g/mol.

The molecular framework of (3S,6S,9S,12R,15S,18S,21S,24S,27R,30S,33S)-27-((2-(Dimethylamino)ethyl)thio)-30-ethyl-33-((1R,2R,E)-1-hydroxy-2-methylhex-4-en-1-yl)-24-(2-hydroxy-2-methylpropyl)-6,9,18-triisobutyl-3,21-diisopropyl-1,4,7,10,12,15,19,25,28-nonamethyl-1,4,7,10,13,16,19,22,25,28,31-undecaazacyclotritriacontan-2,5,8,11,14,17,20,23,26,29,32-undecaone (C66H120N12O13S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone 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).

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.
