Chemical Structure
Description
The occurrence of 1-(2-(Phenylethynyl)phenyl)ethanone is closely related to a hydroxyl group, an ether linkage, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 1-(2-(Phenylethynyl)phenyl)ethanone (CAS 171258-08-5), a certified reference material (molecular formula C16H12O, MW 220.27 g/mol) for analytical method development and quality control.
The molecular framework of 1-(2-(Phenylethynyl)phenyl)ethanone (C16H12O) is characterized by 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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), 1-(2-(Phenylethynyl)phenyl)ethanone 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.
