2,4,4-Trichloro-3-(dichloromethyl)-2-butenoic Acid Methyl Ester 2,4,4-Trichloro-3-(dichloromethyl)crotonic Acid Methyl Ester 97055-36-2 Methyl 2,4,4-Trichloro-3-(dichloromethyl)crotonate (CAS 97055-36-2), molecular formula C6H5Cl5O2 and molecular weight 286.37 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C6H5Cl5O2, 2,4,4-Trichloro-3-(dichloromethyl)-2-butenoic Acid Methyl Ester 2,4,4-Trichloro-3-(dichloromethyl)crotonic Acid Methyl Ester 97055-36-2 Methyl 2,4,4-Trichloro-3-(dichloromethyl)crotonate contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 286.37 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
