Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2,2,3,3,3-Pentafluoro-1-mesitylpropan-1-one (CAS 1443346-16-4) is a high-purity analytical reference standard with the molecular formula C12H11F5O and a molecular weight of 266.21 g/mol.
Structurally, 2,2,3,3,3-Pentafluoro-1-mesitylpropan-1-one (C12H11F5O) contains a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. 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 266.21 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.
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.
