Chemical Structure
Description
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.
2-(3-(Tert-butyl)-5,9-dimethyl-7-oxo-7h-furo[3,2-g]chromen-6-yl)acetic acid (CAS 664366-06-7) is a high-purity analytical reference standard with the molecular formula C19H20O5 and a molecular weight of 328.36 g/mol.
2-(3-(Tert-butyl)-5,9-dimethyl-7-oxo-7h-furo[3,2-g]chromen-6-yl)acetic acid (C19H20O5) contains a flavonoid core, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
