2-(2,3,5,9-Tetramethyl-7-oxo-7h-furo[3,2-g]chromen-6-yl)acetic acid CAS 664366-08-9

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-(2,3,5,9-Tetramethyl-7-oxo-7h-furo[3,2-g]chromen-6-yl)acetic acid.

2-(2,3,5,9-Tetramethyl-7-oxo-7h-furo[3,2-g]chromen-6-yl)acetic acid (CAS 664366-08-9), molecular formula C17H16O5 and molecular weight 300.31 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C17H16O5, 2-(2,3,5,9-Tetramethyl-7-oxo-7h-furo[3,2-g]chromen-6-yl)acetic acid contains a flavonoid core, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 300.31 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).

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.
