Chemical Structure

2-Propenoic acid, 3-[3,4-bis[[(1,1-dimethylethyl)dimethylsilyl]oxy]phenyl]-, (2E) CAS 203118-32-5 chemical structure

Description

The occurrence of 2-Propenoic acid, 3-[3,4-bis[[(1,1-dimethylethyl)dimethylsilyl]oxy]phenyl]-, (2E) 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.

2-Propenoic acid, 3-[3,4-bis[[(1,1-dimethylethyl)dimethylsilyl]oxy]phenyl]-, (2E) (CAS 203118-32-5), molecular formula C21H36O4Si2 and molecular weight 408.68 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 2-Propenoic acid, 3-[3,4-bis[[(1,1-dimethylethyl)dimethylsilyl]oxy]phenyl]-, (2E) (C21H36O4Si2) 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.
