Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (1R,2S)-2-(2-oxo-2-(2-(trifluoromethyl)phenyl)ethyl)cyclopentane-1-carboxylic acid.
(1R,2S)-2-(2-oxo-2-(2-(trifluoromethyl)phenyl)ethyl)cyclopentane-1-carboxylic acid (CAS 733740-73-3), molecular formula C15H15F3O3 and molecular weight 300.27 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C15H15F3O3, (1R,2S)-2-(2-oxo-2-(2-(trifluoromethyl)phenyl)ethyl)cyclopentane-1-carboxylic acid contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 300.27 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
