Chemical Structure
Description
The molecular framework of 4-((4-(Phenylethynyl)phenyl)ethynyl)benzenethiol (C22H14S) is characterized by sulfur-containing functionality, 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.
CATO supplies 4-((4-(Phenylethynyl)phenyl)ethynyl)benzenethiol (CAS 174844-47-4), a certified reference material (molecular formula C22H14S, MW 310.41 g/mol) for analytical method development and quality control.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 4-((4-(Phenylethynyl)phenyl)ethynyl)benzenethiol 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.
