The molecular framework of Ethyl (R)-(-)-2-Hydroxy-4-phenylbutyrate (r)-2-hydroxy-4-phenylbutyric acid ethyl ester (r)-(-)-2-hydroxy-4-phenylbutyric acid ethyl ester (r)-(-)-2-hydroxy-4-phenylbutyrate ethyl ester r(-) ethyl-2-hydroxy-4-phenylbutyrate ethyl (r)-2-hydroxy-4-phenylbutyrate ethyl(r)2-hydroxy-4-phenylbutyrate (r)-ethyl 2-hydroxy-4-phenylbutanoate r-2-hydroxy-4-phenyl butyric acid ethyl ester (r)-2-hydroxy-4-phenylbutyrate (r)-ethyl-4-phenyl-2-hydroxybutyrate ethyl(r)-2-hydroxy-4-phenylbutyrate ethyl-(r)-(-)-2-hydroxy 4-phenylbutyrate (r)-2-hydroxy-4-phenylbutanoic acid ethyl ester (r)-ethyl-2-hydroxy-4-phenylbutyrate ethyl(r)-2-hydroxy-4-phenylbutanoate (r)-ethyl 2-hydroxy-4-phenylbutanate 90315-82-5 (C12H22O3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage. 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
