9-(4,4,5,5-Tetramethyl-1,3,2-dioxaborolan-2-yl)-1,2,3,5,6,7-hexahydropyrido[3,2,1-ij]quinoline CAS 1262331-13-4 chemical structure

Description

CATO supplies 9-(4,4,5,5-Tetramethyl-1,3,2-dioxaborolan-2-yl)-1,2,3,5,6,7-hexahydropyrido[3,2,1-ij]quinoline (CAS 1262331-13-4), a certified reference material (molecular formula C18H26BNO2, MW 299.22 g/mol) for analytical method development and quality control.

9-(4,4,5,5-Tetramethyl-1,3,2-dioxaborolan-2-yl)-1,2,3,5,6,7-hexahydropyrido[3,2,1-ij]quinoline (C18H26BNO2) contains a steroid core, an amide 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
