Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (2R,3S,4S)-5-(((2R,3R,4R,5S)-5-((((2R,3R,4R,5S)-5-((((2R,3R,4R,5S)-5-((((2R,3R,4R,5S)-3,4-dihydroxy-5-(hydroxymethyl)tetrahydrofuran-2-yl)oxy)methyl)-3,4-dihydroxytetrahydrofuran-2-yl)oxy)methyl)-3,4-dihydroxytetrahydrofuran-2-yl)oxy)methyl)-3,4-dihydroxytetrahydrofuran-2-yl)oxy)-2,3,4-trihydroxypentanal.
(2R,3S,4S)-5-(((2R,3R,4R,5S)-5-((((2R,3R,4R,5S)-5-((((2R,3R,4R,5S)-5-((((2R,3R,4R,5S)-3,4-dihydroxy-5-(hydroxymethyl)tetrahydrofuran-2-yl)oxy)methyl)-3,4-dihydroxytetrahydrofuran-2-yl)oxy)methyl)-3,4-dihydroxytetrahydrofuran-2-yl)oxy)methyl)-3,4-dihydroxytetrahydrofuran-2-yl)oxy)-2,3,4-trihydroxypentanal (CAS 190852-25-6) is a high-purity analytical reference standard with the molecular formula C25H42O21 and a molecular weight of 678.59 g/mol.
The molecular framework of (2R,3S,4S)-5-(((2R,3R,4R,5S)-5-((((2R,3R,4R,5S)-5-((((2R,3R,4R,5S)-5-((((2R,3R,4R,5S)-3,4-dihydroxy-5-(hydroxymethyl)tetrahydrofuran-2-yl)oxy)methyl)-3,4-dihydroxytetrahydrofuran-2-yl)oxy)methyl)-3,4-dihydroxytetrahydrofuran-2-yl)oxy)methyl)-3,4-dihydroxytetrahydrofuran-2-yl)oxy)-2,3,4-trihydroxypentanal (C25H42O21) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional 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.
As a certified reference material (CRM), (2R,3S,4S)-5-(((2R,3R,4R,5S)-5-((((2R,3R,4R,5S)-5-((((2R,3R,4R,5S)-5-((((2R,3R,4R,5S)-3,4-dihydroxy-5-(hydroxymethyl)tetrahydrofuran-2-yl)oxy)methyl)-3,4-dihydroxytetrahydrofuran-2-yl)oxy)methyl)-3,4-dihydroxytetrahydrofuran-2-yl)oxy)methyl)-3,4-dihydroxytetrahydrofuran-2-yl)oxy)-2,3,4-trihydroxypentanal 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.
