Chemical Structure

(S)-2-(4-(tert-Butyl)phenyl)propanoic acid CAS 172824-87-2 chemical structure

Description

(S)-2-(4-(tert-Butyl)phenyl)propanoic acid (CAS 172824-87-2), molecular formula C13H18O2 and molecular weight 206.28 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C13H18O2, (S)-2-(4-(tert-Butyl)phenyl)propanoic acid contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 206.28 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
