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 2-(3-Fluoro-5-(trifluoromethyl)thiophen-2-yl)-2-methylpropanoic acid.
2-(3-Fluoro-5-(trifluoromethyl)thiophen-2-yl)-2-methylpropanoic acid (CAS 950604-93-0) is a high-purity analytical reference standard with the molecular formula C9H8F4O2S and a molecular weight of 256.22 g/mol.
The molecular framework of 2-(3-Fluoro-5-(trifluoromethyl)thiophen-2-yl)-2-methylpropanoic acid (C9H8F4O2S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
