Description
CATO supplies 378-81-4 4-chloranyl-1,1,2-tris(fluoranyl)but-1-ene 4-chloro-1,1,2-trifluoro-1-butene A823918 (CAS 378-81-4), a certified reference material (molecular formula C4H4ClF3, MW 144.52 g/mol) for analytical method development and quality control.
378-81-4 4-chloranyl-1,1,2-tris(fluoranyl)but-1-ene 4-chloro-1,1,2-trifluoro-1-butene A823918 (C4H4ClF3) contains fluorine/chlorine substitution. Halogen substitution raises its density and boiling point; 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.
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.
