Chemical Structure
Description
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.
1,2,3-Trifluoro-5-(trans-4-pentylcyclohexyl)benzene (CAS 131819-22-2) is a high-purity analytical reference standard with the molecular formula C17H23F3 and a molecular weight of 284.36 g/mol.
Owing to fluorine substitution, an aromatic ring system, 1,2,3-Trifluoro-5-(trans-4-pentylcyclohexyl)benzene is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 284.36 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
