(R)-1-(2-hydroxy-1-phenylethyl)-3-mesityl-4,5-dihydro-1H-imidazol-3-ium hexafluorophosphate(V) CAS 1982376-77-1 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 454.39 g/mol gives (R)-1-(2-hydroxy-1-phenylethyl)-3-mesityl-4,5-dihydro-1H-imidazol-3-ium hexafluorophosphate(V) distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

(R)-1-(2-hydroxy-1-phenylethyl)-3-mesityl-4,5-dihydro-1H-imidazol-3-ium hexafluorophosphate(V) (CAS 1982376-77-1), molecular formula C20H25N2OF6P and molecular weight 454.39 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a steroid core, an amide group, organophosphorus functionality, a hydroxyl group, an ether linkage, fluorine substitution, (R)-1-(2-hydroxy-1-phenylethyl)-3-mesityl-4,5-dihydro-1H-imidazol-3-ium hexafluorophosphate(V) is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 454.39 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
