Chemical Structure

(S)-3-Methyl-2-phenylbutanoic Acid CAS 13490-69-2 chemical structure

Description

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.

(S)-3-Methyl-2-phenylbutanoic Acid (CAS 13490-69-2), molecular formula C11H14O2 and molecular weight 178.23 g/mol, is a CATO reference standard with documented purity and traceability.

(S)-3-Methyl-2-phenylbutanoic Acid (C11H14O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
