1,1,1,3,3-Pentafluorobutane CAS 406-58-6

Description

The occurrence of 1,1,1,3,3-Pentafluorobutane is closely related to fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1,1,1,3,3-Pentafluorobutane (CAS 406-58-6), molecular formula C4H5F5 and molecular weight 148.07 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 1,1,1,3,3-Pentafluorobutane (C4H5F5) contains fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 0.0, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 148.07 g/mol, it falls into the low-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.

As a certified reference material (CRM), 1,1,1,3,3-Pentafluorobutane 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.
