Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 272.39 g/mol gives 5-(4-Methoxyphenyl)-2,2'-bithiophene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 5-(4-Methoxyphenyl)-2,2'-bithiophene (CAS 106925-79-5), a certified reference material (molecular formula C15H12OS2, MW 272.39 g/mol) for analytical method development and quality control.
The molecular framework of 5-(4-Methoxyphenyl)-2,2'-bithiophene (C15H12OS2) is characterized by sulfur-containing functionality, a hydroxyl group, an ether linkage, 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.
