Description

Compared with other compounds in its class, the molecular weight of 324.22 g/mol gives 4,4,5,5-Tetramethyl-2-(4-((4-methylbenzyl)oxy)phenyl)-1,3,2-dioxaborolane distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

4,4,5,5-Tetramethyl-2-(4-((4-methylbenzyl)oxy)phenyl)-1,3,2-dioxaborolane (CAS 1813554-26-5), molecular formula C20H25BO3 and molecular weight 324.22 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 4,4,5,5-Tetramethyl-2-(4-((4-methylbenzyl)oxy)phenyl)-1,3,2-dioxaborolane (C20H25BO3) is characterized by a steroid core, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.

As a certified reference material (CRM), 4,4,5,5-Tetramethyl-2-(4-((4-methylbenzyl)oxy)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.
