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 1,3-Dimethyl 5,5-dicyano-4-(4-fluorophenyl)-2-hydroxy-6-phenylcyclohex-1-ene-1,3-dicarboxylate.
CATO supplies 1,3-Dimethyl 5,5-dicyano-4-(4-fluorophenyl)-2-hydroxy-6-phenylcyclohex-1-ene-1,3-dicarboxylate (CAS 1212220-50-2), a certified reference material (molecular formula C24H19FN2O5, MW 434.42 g/mol) for analytical method development and quality control.
The molecular framework of 1,3-Dimethyl 5,5-dicyano-4-(4-fluorophenyl)-2-hydroxy-6-phenylcyclohex-1-ene-1,3-dicarboxylate (C24H19FN2O5) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
