8,10-dimethoxy-1,1,10b-trimethyl-5H-oxazolo[4,3-a]phthalazine-3,6-dione CAS 728025-45-4

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.

8,10-dimethoxy-1,1,10b-trimethyl-5H-oxazolo[4,3-a]phthalazine-3,6-dione (CAS 728025-45-4) is a high-purity analytical reference standard with the molecular formula C15H18N2O5 and a molecular weight of 306.31 g/mol.

The molecular framework of 8,10-dimethoxy-1,1,10b-trimethyl-5H-oxazolo[4,3-a]phthalazine-3,6-dione (C15H18N2O5) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
