Description

The occurrence of 402-44-8 Benzene, 1-fluoro-4-(trifluoromethyl)- alpha,alpha,alpha,4-Tetrafluorotoluene EINECS 206-944-1 p-Fluorobenzotrifluoride 4-Fluorobenzotrifluoride p-Fluorotrifluoromethylbenzene 1-Fluoro-4-(trifluoromethyl)benzene NSC 88289 alpha,alpha,alpha,p-Tetrafluorotoluene Toluene, p,alpha,alpha,alpha-tetrafluoro- p-(Trifluoromethyl)fluorobenzene is closely related to fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

402-44-8 Benzene, 1-fluoro-4-(trifluoromethyl)- alpha,alpha,alpha,4-Tetrafluorotoluene EINECS 206-944-1 p-Fluorobenzotrifluoride 4-Fluorobenzotrifluoride p-Fluorotrifluoromethylbenzene 1-Fluoro-4-(trifluoromethyl)benzene NSC 88289 alpha,alpha,alpha,p-Tetrafluorotoluene Toluene, p,alpha,alpha,alpha-tetrafluoro- p-(Trifluoromethyl)fluorobenzene (CAS 402-44-8), molecular formula C7H10F4 and molecular weight 170.15 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 402-44-8 Benzene, 1-fluoro-4-(trifluoromethyl)- alpha,alpha,alpha,4-Tetrafluorotoluene EINECS 206-944-1 p-Fluorobenzotrifluoride 4-Fluorobenzotrifluoride p-Fluorotrifluoromethylbenzene 1-Fluoro-4-(trifluoromethyl)benzene NSC 88289 alpha,alpha,alpha,p-Tetrafluorotoluene Toluene, p,alpha,alpha,alpha-tetrafluoro- p-(Trifluoromethyl)fluorobenzene (C7H10F4) is characterized by fluorine substitution. 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.
