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.
2-(S)-Hydroxy-4-oxo-4-phenylbutyric Acid (CAS 146912-63-2) is a high-purity analytical reference standard with the molecular formula C10H10O4 and a molecular weight of 194.18 g/mol.
The molecular framework of 2-(S)-Hydroxy-4-oxo-4-phenylbutyric Acid (C10H10O4) 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
CATO manufactures 2-(S)-Hydroxy-4-oxo-4-phenylbutyric Acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
