142299-73-8 Phenanthro[3,2-b]furan-3,6(2H,4H)-dione,1,11b-dihydro-5,7,11-trihydroxy-4,4,9,11b-tetramethyl-, (11bR)- CAS 142299-73-8

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 142299-73-8 Phenanthro[3,2-b]furan-3,6(2H,4H)-dione,1,11b-dihydro-5,7,11-trihydroxy-4,4,9,11b-tetramethyl-, (11bR)-.

142299-73-8 Phenanthro[3,2-b]furan-3,6(2H,4H)-dione,1,11b-dihydro-5,7,11-trihydroxy-4,4,9,11b-tetramethyl-, (11bR)- (CAS 142299-73-8), molecular formula C20H20O6 and molecular weight 356.37 g/mol, is a CATO reference standard with documented purity and traceability.

142299-73-8 Phenanthro[3,2-b]furan-3,6(2H,4H)-dione,1,11b-dihydro-5,7,11-trihydroxy-4,4,9,11b-tetramethyl-, (11bR)- (C20H20O6) 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.
