Chemical Structure
Description
As a certified reference material (CRM), 2-(Hydroxy(4-methoxyphenyl)methylene)-1H-indene-1,3(2H)-dione 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-(Hydroxy(4-methoxyphenyl)methylene)-1H-indene-1,3(2H)-dione (CAS 860784-13-0) is a high-purity analytical reference standard with the molecular formula C17H12O4 and a molecular weight of 280.27 g/mol.
The molecular framework of 2-(Hydroxy(4-methoxyphenyl)methylene)-1H-indene-1,3(2H)-dione (C17H12O4) is characterized by a flavonoid 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.
