Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (1S,2S)-2-[4-(Trifluoromethyl)phenyl]cyclopropanecarboxylic Acid.
(1S,2S)-2-[4-(Trifluoromethyl)phenyl]cyclopropanecarboxylic Acid (CAS 201164-20-7) is a high-purity analytical reference standard with the molecular formula C11H9F3O2 and a molecular weight of 230.18 g/mol.
Based on its molecular formula C11H9F3O2, (1S,2S)-2-[4-(Trifluoromethyl)phenyl]cyclopropanecarboxylic Acid contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 230.18 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.
