Chemical Structure
Description
As a certified reference material (CRM), (2-(4-(prop-2-yn-1-yloxy)phenyl)ethene-1,1,2-triyl)tribenzene 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.
(2-(4-(prop-2-yn-1-yloxy)phenyl)ethene-1,1,2-triyl)tribenzene (CAS 1644078-88-5), molecular formula C29H22O and molecular weight 386.48 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (2-(4-(prop-2-yn-1-yloxy)phenyl)ethene-1,1,2-triyl)tribenzene (C29H22O) is characterized by a steroid core, a hydroxyl group, an ether linkage. 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.
