Description
As a certified reference material (CRM), 2-((3-Benzyl-6-chloro-4-methyl-2-oxo-2H-chromen-7-yl)oxy)propanoic acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
2-((3-Benzyl-6-chloro-4-methyl-2-oxo-2H-chromen-7-yl)oxy)propanoic acid (CAS 1017420-72-2) is a high-purity analytical reference standard with the molecular formula C20H17ClO5 and a molecular weight of 372.80 g/mol.
Based on its molecular formula C20H17ClO5, 2-((3-Benzyl-6-chloro-4-methyl-2-oxo-2H-chromen-7-yl)oxy)propanoic acid 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 372.80 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
