Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 1,4-Dichloro-5,6,7,8-tetrahydro-5,8-ethanophthalazine (CAS 202823-67-4), a certified reference material (molecular formula C10H10Cl2N2, MW 229.11 g/mol) for analytical method development and quality control.
Based on its molecular formula C10H10Cl2N2, 1,4-Dichloro-5,6,7,8-tetrahydro-5,8-ethanophthalazine contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 229.11 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
