Chemical Structure
Description
The molecular framework of 2-Phenylbutyric Acid-d5 (C10H7D5O2) is characterized by deuterium isotope labeling, 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).
2-Phenylbutyric Acid-d5 (CAS 1189708-92-6) is a high-purity analytical reference standard with the molecular formula C10H7D5O2 and a molecular weight of 169.23 g/mol.
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.
