Compared with other compounds in its class, the molecular weight of 584.92 g/mol gives (1,1,5,5-Tetramethyl-3,3-diphenyltrisiloxane-1,5-diyl)bis(propane-3,1-diyl) bis(2-methylacrylate) distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies (1,1,5,5-Tetramethyl-3,3-diphenyltrisiloxane-1,5-diyl)bis(propane-3,1-diyl) bis(2-methylacrylate) (CAS 1581235-15-5), a certified reference material (molecular formula C30H44O6Si3, MW 584.92 g/mol) for analytical method development and quality control.
The molecular framework of (1,1,5,5-Tetramethyl-3,3-diphenyltrisiloxane-1,5-diyl)bis(propane-3,1-diyl) bis(2-methylacrylate) (C30H44O6Si3) is characterized by a steroid core, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, 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.
