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 (1R,2S)-2-(2-(2-fluorophenyl)-2-oxoethyl)cyclohexane-1-carboxylic acid.
(1R,2S)-2-(2-(2-fluorophenyl)-2-oxoethyl)cyclohexane-1-carboxylic acid (CAS 735274-94-9) is a high-purity analytical reference standard with the molecular formula C15H17FO3 and a molecular weight of 264.29 g/mol.
Structurally, (1R,2S)-2-(2-(2-fluorophenyl)-2-oxoethyl)cyclohexane-1-carboxylic acid (C15H17FO3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 264.29 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
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.
