3-(4,4,5,5-Tetramethyl-1,3,2-dioxaborolan-2-yl)-1-(trimethylsilyl)-1H-pyrrole CAS 1802557-92-1

Description

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.

3-(4,4,5,5-Tetramethyl-1,3,2-dioxaborolan-2-yl)-1-(trimethylsilyl)-1H-pyrrole (CAS 1802557-92-1), molecular formula C13H24BNO2Si and molecular weight 265.23 g/mol, is a CATO reference standard with documented purity and traceability.

3-(4,4,5,5-Tetramethyl-1,3,2-dioxaborolan-2-yl)-1-(trimethylsilyl)-1H-pyrrole (C13H24BNO2Si) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
