Chemical Structure
Description
1,2,3-Trifluoro-5-[trans-4-[2-(trans-4-propylcyclohexyl)ethyl]cyclohexyl]benzene (CAS 131819-24-4) is a high-purity analytical reference standard with the molecular formula C23H33F3 and a molecular weight of 366.50 g/mol.
Based on its molecular formula C23H33F3, 1,2,3-Trifluoro-5-[trans-4-[2-(trans-4-propylcyclohexyl)ethyl]cyclohexyl]benzene contains fluorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 366.50 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
