2-(3-Chloroprop-1-en-1-yl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane 873077-21-5 ST24039309 (CAS 873077-21-5), molecular formula C9H16BClO2 and molecular weight 202.49 g/mol, is a CATO reference standard with documented purity and traceability.
2-(3-Chloroprop-1-en-1-yl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane 873077-21-5 ST24039309 (C9H16BClO2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. 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.
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.
