Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-((2R,5S,8S,11S,14S,17S,20S)-8,11-Diisobutyl-14-((1-methoxy-1H-indol-3-yl)methyl)-7,13,19,20-tetramethyl-5,17-bis((R)-2-methylhexyl)-3,6,9,12,15,18,21-heptaoxo-1-oxa-4,7,10,13,16,19-hexaazacyclohenicosan-2-yl)propanenitrile.
3-((2R,5S,8S,11S,14S,17S,20S)-8,11-Diisobutyl-14-((1-methoxy-1H-indol-3-yl)methyl)-7,13,19,20-tetramethyl-5,17-bis((R)-2-methylhexyl)-3,6,9,12,15,18,21-heptaoxo-1-oxa-4,7,10,13,16,19-hexaazacyclohenicosan-2-yl)propanenitrile (CAS 165754-55-2) is a high-purity analytical reference standard with the molecular formula C53H84N8O9 and a molecular weight of 977.28 g/mol.
Structurally, 3-((2R,5S,8S,11S,14S,17S,20S)-8,11-Diisobutyl-14-((1-methoxy-1H-indol-3-yl)methyl)-7,13,19,20-tetramethyl-5,17-bis((R)-2-methylhexyl)-3,6,9,12,15,18,21-heptaoxo-1-oxa-4,7,10,13,16,19-hexaazacyclohenicosan-2-yl)propanenitrile (C53H84N8O9) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 16.0, corresponding to approximately 16 ring(s) or double-bond equivalent(s). With a molecular weight of 977.28 g/mol, it falls into the 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.
As a certified reference material (CRM), 3-((2R,5S,8S,11S,14S,17S,20S)-8,11-Diisobutyl-14-((1-methoxy-1H-indol-3-yl)methyl)-7,13,19,20-tetramethyl-5,17-bis((R)-2-methylhexyl)-3,6,9,12,15,18,21-heptaoxo-1-oxa-4,7,10,13,16,19-hexaazacyclohenicosan-2-yl)propanenitrile meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
