Chemical Structure

4,4,5,5-Tetramethyl-2-(3-(pentyloxy)phenyl)-1,3,2-dioxaborolane CAS 2490666-19-6 chemical structure

Description

4,4,5,5-Tetramethyl-2-(3-(pentyloxy)phenyl)-1,3,2-dioxaborolane (C17H27BO3) contains a steroid core, 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

4,4,5,5-Tetramethyl-2-(3-(pentyloxy)phenyl)-1,3,2-dioxaborolane (CAS 2490666-19-6), molecular formula C17H27BO3 and molecular weight 290.21 g/mol, is a CATO reference standard with documented purity and traceability.

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.

As a certified reference material (CRM), 4,4,5,5-Tetramethyl-2-(3-(pentyloxy)phenyl)-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.
