1,1'-((Oxybis(methylene))bis(5-chloro-2-hydroxy-3,1-phenylene))diethanone CAS 50525-73-0

Description

Based on its molecular formula C18H16Cl2O5, 1,1'-((Oxybis(methylene))bis(5-chloro-2-hydroxy-3,1-phenylene))diethanone contains a flavonoid core, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 383.22 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).

1,1'-((Oxybis(methylene))bis(5-chloro-2-hydroxy-3,1-phenylene))diethanone (CAS 50525-73-0), molecular formula C18H16Cl2O5 and molecular weight 383.22 g/mol, is a CATO reference standard with documented purity and traceability.

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.
