The molecular framework of (3R,4S,5R)-3,4-Dihydroxy-5-((1S,2R)-1,2,3-trihydroxypropyl)dihydrofuran-2(3H)-one (C7H12O7) is characterized by a carbohydrate-derived structure. 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.
(3R,4S,5R)-3,4-Dihydroxy-5-((1S,2R)-1,2,3-trihydroxypropyl)dihydrofuran-2(3H)-one (CAS 221129-03-9), molecular formula C7H12O7 and molecular weight 208.17 g/mol, is a CATO reference standard with documented purity and traceability.
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.
