Chemical Structure
Description
The molecular framework of 3-O-[(tert-Butyldiphenylsilyl]-6-O-(D,L-1-Ethoxyethyl)-1,2:4,5-bis-O-(1-methylethylidene)-D,L-myo-inositol (C32H46O7Si) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. 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).
3-O-[(tert-Butyldiphenylsilyl]-6-O-(D,L-1-Ethoxyethyl)-1,2:4,5-bis-O-(1-methylethylidene)-D,L-myo-inositol (CAS 197848-72-9), molecular formula C32H46O7Si and molecular weight 570.79 g/mol, is a CATO reference standard with documented purity and traceability.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
