Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2,3,5,6-Tetramethyl-2,2,2-trifluoroacetophenone (CAS 1143461-70-4) is a high-purity analytical reference standard with the molecular formula C12H13F3O and a molecular weight of 230.23 g/mol.
Owing to a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system, 2,3,5,6-Tetramethyl-2,2,2-trifluoroacetophenone is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 230.23 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.
CATO manufactures 2,3,5,6-Tetramethyl-2,2,2-trifluoroacetophenone under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
