Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 260.15 g/mol gives 4-(Heptafluoroisopropyl)toluene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
4-(Heptafluoroisopropyl)toluene (CAS 2396-26-1) is a high-purity analytical reference standard with the molecular formula C10H7F7 and a molecular weight of 260.15 g/mol.
Based on its molecular formula C10H7F7, 4-(Heptafluoroisopropyl)toluene contains fluorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 260.15 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.
