The occurrence of (2R)-2,3-Dihydroxy-3-methylbutanoic acid is closely related to a carbohydrate-derived structure in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(2R)-2,3-Dihydroxy-3-methylbutanoic acid (CAS 19451-56-0) is a high-purity analytical reference standard with the molecular formula C5H10O4 and a molecular weight of 134.13 g/mol.
The molecular framework of (2R)-2,3-Dihydroxy-3-methylbutanoic acid (C5H10O4) 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.
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.
