Chemical Structure

4-Ethyl-2'-fluoro-4''-pentyl-1,1':4',1''-terphenyl CAS 95759-61-8 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 346.48 g/mol gives 4-Ethyl-2'-fluoro-4''-pentyl-1,1':4',1''-terphenyl distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 4-Ethyl-2'-fluoro-4''-pentyl-1,1':4',1''-terphenyl (CAS 95759-61-8), a certified reference material (molecular formula C25H27F, MW 346.48 g/mol) for analytical method development and quality control.

Structurally, 4-Ethyl-2'-fluoro-4''-pentyl-1,1':4',1''-terphenyl (C25H27F) contains fluorine substitution, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 346.48 g/mol, it falls into the moderately-high-molecular-weight range. 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.
