Chemical Structure

2-(4-Secbutylphenyl)propionic acid CAS 64951-76-9 chemical structure

Description

CATO supplies 2-(4-Secbutylphenyl)propionic acid (CAS 64951-76-9), a certified reference material (molecular formula C13H18O2, MW 206.28 g/mol) for analytical method development and quality control.

2-(4-Secbutylphenyl)propionic acid (C13H18O2) 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 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).

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.
