2-(1,3-Dioxo-2-phenyl-2,3-dihydro-1H-inden-2-yl)acetic acid CAS 7443-02-9 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 2-(1,3-Dioxo-2-phenyl-2,3-dihydro-1H-inden-2-yl)acetic acid.

2-(1,3-Dioxo-2-phenyl-2,3-dihydro-1H-inden-2-yl)acetic acid (CAS 7443-02-9) is a high-purity analytical reference standard with the molecular formula C17H12O4 and a molecular weight of 280.27 g/mol.

2-(1,3-Dioxo-2-phenyl-2,3-dihydro-1H-inden-2-yl)acetic acid (C17H12O4) contains a flavonoid core, a hydroxyl group, an ether linkage. 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. 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.
