1,1,1,3,5,5,5-Heptafluoropentane-2,2,4,4-tetraol CAS 77953-71-0

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1,1,1,3,5,5,5-Heptafluoropentane-2,2,4,4-tetraol.

1,1,1,3,5,5,5-Heptafluoropentane-2,2,4,4-tetraol (CAS 77953-71-0) is a high-purity analytical reference standard with the molecular formula C5H5F7O4 and a molecular weight of 262.08 g/mol.

The molecular framework of 1,1,1,3,5,5,5-Heptafluoropentane-2,2,4,4-tetraol (C5H5F7O4) is characterized by a carbohydrate-derived structure, 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.

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.
