Chemical Structure
Description
(1R,2S)-2-(2-oxo-2-(p-tolyl)ethyl)cyclopentane-1-carboxylic acid (CAS 733740-54-0) is a high-purity analytical reference standard with the molecular formula C15H18O3 and a molecular weight of 246.30 g/mol.
The molecular framework of (1R,2S)-2-(2-oxo-2-(p-tolyl)ethyl)cyclopentane-1-carboxylic acid (C15H18O3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic 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).
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.
