5-(2,2,2-Trifluoroethoxy)-3,4-dihydronaphthalen-1(2H)-one CAS 1466429-90-2

Description

5-(2,2,2-Trifluoroethoxy)-3,4-dihydronaphthalen-1(2H)-one (CAS 1466429-90-2), molecular formula C12H11F3O2 and molecular weight 244.21 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 5-(2,2,2-Trifluoroethoxy)-3,4-dihydronaphthalen-1(2H)-one (C12H11F3O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 244.21 g/mol, it falls into the medium-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.

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.
