2',3,5-Trifluoro-4''-propyl-[1,1':4',1''-terphenyl]-4-ol CAS 953049-31-5 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 2',3,5-Trifluoro-4''-propyl-[1,1':4',1''-terphenyl]-4-ol.

2',3,5-Trifluoro-4''-propyl-[1,1':4',1''-terphenyl]-4-ol (CAS 953049-31-5), molecular formula C21H17F3 and molecular weight 326.35 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 2',3,5-Trifluoro-4''-propyl-[1,1':4',1''-terphenyl]-4-ol (C21H17F3) is characterized by fluorine substitution, a polycyclic aromatic system. 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.

CATO manufactures 2',3,5-Trifluoro-4''-propyl-[1,1':4',1''-terphenyl]-4-ol under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
