Chemical Structure
Description
The occurrence of 1H-Undecafluoropentane is closely related to fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
1H-Undecafluoropentane (CAS 375-61-1), molecular formula C5HF11 and molecular weight 270.04 g/mol, is a CATO reference standard with documented purity and traceability.
1H-Undecafluoropentane (C5HF11) contains fluorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
As a certified reference material (CRM), 1H-Undecafluoropentane meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
