Description
As a certified reference material (CRM), 1,1,1-Trifluoro-4-(methylsulfonyl)butan-2-ol meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
1,1,1-Trifluoro-4-(methylsulfonyl)butan-2-ol (CAS 1340311-06-9) is a high-purity analytical reference standard with the molecular formula C5H9F3O3S and a molecular weight of 206.18 g/mol.
1,1,1-Trifluoro-4-(methylsulfonyl)butan-2-ol (C5H9F3O3S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
