7-Chloro-2,2,3,3,4,4,5,5,6,6,7,7-dodecafluoroheptanoyl fluoride CAS 662-63-5

Description

The occurrence of 7-Chloro-2,2,3,3,4,4,5,5,6,6,7,7-dodecafluoroheptanoyl fluoride is closely related to a hydroxyl group, an ether linkage, fluorine/chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

7-Chloro-2,2,3,3,4,4,5,5,6,6,7,7-dodecafluoroheptanoyl fluoride (CAS 662-63-5) is a high-purity analytical reference standard with the molecular formula C7ClF13O and a molecular weight of 382.51 g/mol.

Based on its molecular formula C7ClF13O, 7-Chloro-2,2,3,3,4,4,5,5,6,6,7,7-dodecafluoroheptanoyl fluoride contains a hydroxyl group, an ether linkage, fluorine/chlorine substitution; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 382.51 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
