3-O-tert-butyldimethylsilyl-4,6-o-benzylidene-d-glucal CAS 120120-65-2 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-O-tert-butyldimethylsilyl-4,6-o-benzylidene-d-glucal.

3-O-tert-butyldimethylsilyl-4,6-o-benzylidene-d-glucal (CAS 120120-65-2), molecular formula C19H28O4Si and molecular weight 348.51 g/mol, is a CATO reference standard with documented purity and traceability.

3-O-tert-butyldimethylsilyl-4,6-o-benzylidene-d-glucal (C19H28O4Si) contains a steroid core, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.

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.
