Chemical Structure

1,3:2,4-Dibenzylidene Sorbitol CAS 32647-67-9 chemical structure

Description

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.

1,3:2,4-Dibenzylidene Sorbitol (CAS 32647-67-9), molecular formula C6H14O6C7H8O2 and molecular weight 306.31 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 1,3:2,4-Dibenzylidene Sorbitol (C6H14O6C7H8O2) is characterized by a carboxylic acid group, 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 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).

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.
