3,4,5-Trihydroxy-2-((3,7,8-trihydroxy-5,10-dioxo-5,10-dihydrochromeno[5,4,3-cde]chromen-2-yl)oxy)benzoic acid CAS 60202-70-2

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3,4,5-Trihydroxy-2-((3,7,8-trihydroxy-5,10-dioxo-5,10-dihydrochromeno[5,4,3-cde]chromen-2-yl)oxy)benzoic acid.

3,4,5-Trihydroxy-2-((3,7,8-trihydroxy-5,10-dioxo-5,10-dihydrochromeno[5,4,3-cde]chromen-2-yl)oxy)benzoic acid (CAS 60202-70-2) is a high-purity analytical reference standard with the molecular formula C21H10O13 and a molecular weight of 470.30 g/mol.

Structurally, 3,4,5-Trihydroxy-2-((3,7,8-trihydroxy-5,10-dioxo-5,10-dihydrochromeno[5,4,3-cde]chromen-2-yl)oxy)benzoic acid (C21H10O13) contains a flavonoid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 17.0, corresponding to approximately 17 ring(s) or double-bond equivalent(s). With a molecular weight of 470.30 g/mol, it falls into the moderately-high-molecular-weight range. 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.
