Chemical Structure

1,3:2,4-Di-p-methylbenyliedene Sorbitol CAS 54686-97-4 chemical structure

Description

1,3:2,4-Di-p-methylbenyliedene Sorbitol (CAS 54686-97-4) is a high-purity analytical reference standard with the molecular formula C22H38O6 and a molecular weight of 398.53 g/mol.

Based on its molecular formula C22H38O6, 1,3:2,4-Di-p-methylbenyliedene Sorbitol contains a steroid core, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 398.53 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
