3-(3-bicyclo[4.2.0]octa-1,3,5-trienyl)propanoyl chloride (CAS 2271393-81-6), molecular formula C11H17ClO and molecular weight 200.71 g/mol, is a CATO reference standard with documented purity and traceability.
3-(3-bicyclo[4.2.0]octa-1,3,5-trienyl)propanoyl chloride (C11H17ClO) contains a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; 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.
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.
