Chemical Structure

1,3-Dibenzylidene-2-cyclohexanone CAS 897-78-9 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 1,3-Dibenzylidene-2-cyclohexanone.

1,3-Dibenzylidene-2-cyclohexanone (CAS 897-78-9), molecular formula C20H18O and molecular weight 274.36 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C20H18O, 1,3-Dibenzylidene-2-cyclohexanone 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 274.36 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
