2-Chloro-1,3-bis(3-methoxyphenyl)propane-1,3-dione CAS 832739-63-6

Description

2-Chloro-1,3-bis(3-methoxyphenyl)propane-1,3-dione (C17H15ClO4) contains a flavonoid core, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

2-Chloro-1,3-bis(3-methoxyphenyl)propane-1,3-dione (CAS 832739-63-6) is a high-purity analytical reference standard with the molecular formula C17H15ClO4 and a molecular weight of 318.75 g/mol.

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.
