1,1,1-Triphenyl-2,5,8,11,14,17,20-heptaoxadocosan-22-ol CAS 745048-17-3 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1,1,1-Triphenyl-2,5,8,11,14,17,20-heptaoxadocosan-22-ol.

1,1,1-Triphenyl-2,5,8,11,14,17,20-heptaoxadocosan-22-ol (CAS 745048-17-3), molecular formula C33H44O8 and molecular weight 568.70 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 1,1,1-Triphenyl-2,5,8,11,14,17,20-heptaoxadocosan-22-ol (C33H44O8) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, 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), 1,1,1-Triphenyl-2,5,8,11,14,17,20-heptaoxadocosan-22-ol 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.
