Compared with other compounds in its class, the molecular weight of 210.08 g/mol gives 2-((1E,3E)-4-Methoxybuta-1,3-dien-1-yl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-((1E,3E)-4-Methoxybuta-1,3-dien-1-yl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (CAS 540777-96-6), molecular formula C11H19BO3 and molecular weight 210.08 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-((1E,3E)-4-Methoxybuta-1,3-dien-1-yl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (C11H19BO3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
