2,2,2-Trichloroethanol (CAS 115-20-8), molecular formula C2H3Cl3O and molecular weight 149.40 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a hydroxyl group, an ether linkage, chlorine substitution, 2,2,2-Trichloroethanol is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 149.40 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
