Chemical Structure
Description
The occurrence of (3β)-3-[(tert-Butyldimethylsilyl)oxy]-chola-5,7-dien-24-oic Acid Methyl Ester is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(3β)-3-[(tert-Butyldimethylsilyl)oxy]-chola-5,7-dien-24-oic Acid Methyl Ester (CAS 146177-13-1) is a high-purity analytical reference standard with the molecular formula C31H52O3Si and a molecular weight of 500.83 g/mol.
The molecular framework of (3β)-3-[(tert-Butyldimethylsilyl)oxy]-chola-5,7-dien-24-oic Acid Methyl Ester (C31H52O3Si) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
