Chemical Structure
Description
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.
(S)-2-(Benzyloxy)-1-((S)-2,2-dimethyl-1,3-dioxolan-4-yl)ethanol (CAS 117399-58-3), molecular formula C14H20O4 and molecular weight 252.31 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (S)-2-(Benzyloxy)-1-((S)-2,2-dimethyl-1,3-dioxolan-4-yl)ethanol (C14H20O4) 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 its high hydrophobicity (logP), 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).
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.
