3,5,7-Trihydroxy-2-(4-hydroxy-3-(3-methylbut-2-en-1-yl)phenyl)-6-(3-methylbut-2-en-1-yl)-4H-chromen-4-one CAS 142474-52-0

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3,5,7-Trihydroxy-2-(4-hydroxy-3-(3-methylbut-2-en-1-yl)phenyl)-6-(3-methylbut-2-en-1-yl)-4H-chromen-4-one.

3,5,7-Trihydroxy-2-(4-hydroxy-3-(3-methylbut-2-en-1-yl)phenyl)-6-(3-methylbut-2-en-1-yl)-4H-chromen-4-one (CAS 142474-52-0), molecular formula C25H26O6 and molecular weight 422.47 g/mol, is a CATO reference standard with documented purity and traceability.

3,5,7-Trihydroxy-2-(4-hydroxy-3-(3-methylbut-2-en-1-yl)phenyl)-6-(3-methylbut-2-en-1-yl)-4H-chromen-4-one (C25H26O6) 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.

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.
