Description

Compared with other compounds in its class, the molecular weight of 210.08 g/mol gives 2-(3,6-DIHYDRO-2H-PYRAN-4-YL)-4,4,5,5-TETRAMETHYL-1,3,2-DIOXABOROLANE 287944-16-5 3,6-DIHYDRO-2H-PYRAN-4-BORONIC ACID PINACOL ESTER 4-(4,4,5,5-TETRAMETHYL-1,3,2-DIOXABOROLAN-2-YL)-3,6-DIHYDRO-2H-PYRAN BC000313 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-(3,6-DIHYDRO-2H-PYRAN-4-YL)-4,4,5,5-TETRAMETHYL-1,3,2-DIOXABOROLANE 287944-16-5 3,6-DIHYDRO-2H-PYRAN-4-BORONIC ACID PINACOL ESTER 4-(4,4,5,5-TETRAMETHYL-1,3,2-DIOXABOROLAN-2-YL)-3,6-DIHYDRO-2H-PYRAN BC000313 (CAS 287944-16-5), molecular formula C11H19BO3 and molecular weight 210.08 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C11H19BO3, 2-(3,6-DIHYDRO-2H-PYRAN-4-YL)-4,4,5,5-TETRAMETHYL-1,3,2-DIOXABOROLANE 287944-16-5 3,6-DIHYDRO-2H-PYRAN-4-BORONIC ACID PINACOL ESTER 4-(4,4,5,5-TETRAMETHYL-1,3,2-DIOXABOROLAN-2-YL)-3,6-DIHYDRO-2H-PYRAN BC000313 contains a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 210.08 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
