Chemical Structure

2',5'-Di((Z)-styryl)-1,1':4',1''-terphenyl CAS 842170-19-8 chemical structure

Description

2',5'-Di((Z)-styryl)-1,1':4',1''-terphenyl (CAS 842170-19-8), molecular formula C34H26 and molecular weight 434.57 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 2',5'-Di((Z)-styryl)-1,1':4',1''-terphenyl (C34H26) is characterized by 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
