4,4,5,5-Tetramethyl-2-(spiro[fluorene-9,9'-xanthen]-2-yl)-1,3,2-dioxaborolane CAS 1160862-12-3

Description

As a certified reference material (CRM), 4,4,5,5-Tetramethyl-2-(spiro[fluorene-9,9'-xanthen]-2-yl)-1,3,2-dioxaborolane meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.

4,4,5,5-Tetramethyl-2-(spiro[fluorene-9,9'-xanthen]-2-yl)-1,3,2-dioxaborolane (CAS 1160862-12-3), molecular formula C31H27BO3 and molecular weight 458.36 g/mol, is a CATO reference standard with documented purity and traceability.

4,4,5,5-Tetramethyl-2-(spiro[fluorene-9,9'-xanthen]-2-yl)-1,3,2-dioxaborolane (C31H27BO3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. 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.
