4,4,5,5-Tetramethyl-2-(4-octylphenyl)-1,3,2-dioxaborolane CAS 378223-65-5

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4,4,5,5-Tetramethyl-2-(4-octylphenyl)-1,3,2-dioxaborolane.

4,4,5,5-Tetramethyl-2-(4-octylphenyl)-1,3,2-dioxaborolane (CAS 378223-65-5), molecular formula C20H33BO2 and molecular weight 316.29 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 4,4,5,5-Tetramethyl-2-(4-octylphenyl)-1,3,2-dioxaborolane (C20H33BO2) 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).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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