Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4,7-Dichloropyrrolo[1,2-a]quinoxaline.
CATO supplies 4,7-Dichloropyrrolo[1,2-a]quinoxaline (CAS 160657-03-4), a certified reference material (molecular formula C11H6Cl2N2, MW 237.08 g/mol) for analytical method development and quality control.
4,7-Dichloropyrrolo[1,2-a]quinoxaline (C11H6Cl2N2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
