Chemical Structure
Description
The occurrence of 2,2-Dimethyl-1,3-diphenylpropane-1,3-dione is closely related to a steroid core, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 2,2-Dimethyl-1,3-diphenylpropane-1,3-dione (CAS 41169-42-0), a certified reference material (molecular formula C17H16O2, MW 252.31 g/mol) for analytical method development and quality control.
The molecular framework of 2,2-Dimethyl-1,3-diphenylpropane-1,3-dione (C17H16O2) 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 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.
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.
