Chemical Structure

Ubiquinone Q3 CAS 1173-76-8 chemical structure

Description

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.

CATO supplies Ubiquinone Q3 (CAS 1173-76-8), a certified reference material (molecular formula C24H34O4, MW 386.52 g/mol) for analytical method development and quality control.

The molecular framework of Ubiquinone Q3 (C24H34O4) is characterized by a flavonoid 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).

As a certified reference material (CRM), Ubiquinone Q3 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.
