Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 512.59 g/mol gives 25,26,26,26,27,27,27-Heptafluorocholesterol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 25,26,26,26,27,27,27-Heptafluorocholesterol (CAS 153463-21-9), a certified reference material (molecular formula C27H39F7O, MW 512.59 g/mol) for analytical method development and quality control.
Structurally, 25,26,26,26,27,27,27-Heptafluorocholesterol (C27H39F7O) contains a steroid core, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 512.59 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
