2-Amino-4-[3-methoxy-4-(propan-2-yloxy)phenyl]-7-methyl-5-oxo-4H,5H-pyrano[3,2-c]pyran-3-carbonitrile CAS 625375-34-0 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-Amino-4-[3-methoxy-4-(propan-2-yloxy)phenyl]-7-methyl-5-oxo-4H,5H-pyrano[3,2-c]pyran-3-carbonitrile.

2-Amino-4-[3-methoxy-4-(propan-2-yloxy)phenyl]-7-methyl-5-oxo-4H,5H-pyrano[3,2-c]pyran-3-carbonitrile (CAS 625375-34-0) is a high-purity analytical reference standard with the molecular formula C20H20N2O5 and a molecular weight of 368.38 g/mol.

Based on its molecular formula C20H20N2O5, 2-Amino-4-[3-methoxy-4-(propan-2-yloxy)phenyl]-7-methyl-5-oxo-4H,5H-pyrano[3,2-c]pyran-3-carbonitrile contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 368.38 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.

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.
