Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 6-Amino-4-(3-ethoxy-4-(2-morpholinoethoxy)phenyl)-3-ethyl-2,4-dihydropyrano[2,3-c]pyrazole-5-carbonitrile.
6-Amino-4-(3-ethoxy-4-(2-morpholinoethoxy)phenyl)-3-ethyl-2,4-dihydropyrano[2,3-c]pyrazole-5-carbonitrile (CAS 445382-07-0), molecular formula C23H29N5O4 and molecular weight 439.51 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C23H29N5O4, 6-Amino-4-(3-ethoxy-4-(2-morpholinoethoxy)phenyl)-3-ethyl-2,4-dihydropyrano[2,3-c]pyrazole-5-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 439.51 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.
