Chemical Structure
Description
The occurrence of (3,3,4,4-Tetrafluorocyclobut-1-en-1-yl)benzene is closely related to fluorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(3,3,4,4-Tetrafluorocyclobut-1-en-1-yl)benzene (CAS 313-28-0), molecular formula C10H6F4 and molecular weight 202.15 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, (3,3,4,4-Tetrafluorocyclobut-1-en-1-yl)benzene (C10H6F4) contains fluorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 202.15 g/mol, it falls into the medium-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
