Chemical Structure

1,2,5,6-Di-O-cyclohexylidene-alpha-D-glucofuranose CAS 23397-76-4 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

1,2,5,6-Di-O-cyclohexylidene-alpha-D-glucofuranose (CAS 23397-76-4), molecular formula C18H28O6 and molecular weight 340.41 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C18H28O6, 1,2,5,6-Di-O-cyclohexylidene-alpha-D-glucofuranose 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 340.41 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).

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.
